I have both, I find it the round Lazy Susan to have less wasted space, but it really depends on what works with your optimal layout.

What Scrappy said. I ended up closing off a corner completely, so I could have drawers on each side. My kitchen isn't very big, and I tried for months to figure out a way to use the space in that corner, but in the end what I realized I needed most was more drawers, not more space for large or less-used things.

I currently have (and will have again in my new kitchen) the hinged corner cabinet without the lazy susan. As I keep baking pans etc in there, they are large and oddly shaped and I don't think would work with the lazy susan. I am putting a lazy susan in another bottom corner where I store smaller things. In the 2 upper corner cabinets, I'm going without the lazy susan as well, to maximize storage.

Thanks all, I think the corner hinged door is my best bet. I think I will have to get look at them in person to see if I'm better off with the Susan or fixed shelves.

Another option with the corner hinged door is to get the shelves and then add third-party wooden super susans. But you need to do this before the counters go on.

ETA Example, not necessarily advocating this one:

I have two of the Lazy susans from Ikea in my kitchen. I like them very much. They worked better with my layout than the longer corner units.

The shelves are very sturdy. I have quite a bit on both including some heavier things. I love being able to access everything quickly.

Thanks for the pic, it's helpful to see it in the wild.

So I'm not clear on this, is a super Susan the one with the angled hinged door and the shelves have the piece of pie cut out?

And a regular lazy Susan is the diagonal door with full round shelf?

Edit-I looked it up, the super Susan has no center pole, makes sense.

That's right. The ikea susan is on a center pole and you have that instead of shelves. The super susans sit on a regular shelf and have a pie-shaped piece cut out so the door will close.

Pictures are always our friends -- this is a Lazy Susan; note that all the weight is supported by one center pole, and one turntable at the base manages all the weight:

In contrast, this is a Super Susan; the two turntables each rest on a shelf, and their turning mechanisms are completely separate:

Thanks for the pics mrspete! One of my best friends just built a beautiful custom home and I got the fun job of unpacking her kitchen. I had a blast in a kitchen that probably cost close to what my whole house cost lol. Anyway she had one of those LeMans corners. I will say it was the one part of her fabulous kitchen I didn't love. An awkward shape to use. The mechanism and shelves were top of the line, so they worked beautifully but I had trouble getting stuff in there in a logical way.

Your last pic looks like the sturdiest for my purposes but I'm not sure if I can modify an IKEA cabinet to get it to work. Guess I'll find out when I make the trip to IKEA.

Lazy Susan

• The nice thing about a "lazy" susan with the center pole is that the door can be attached to the shelves and rotate in when opened (Kelleg69's picture). That eliminates the piano-hinge doors that can bang against cabinets on the side.
• When the door is attached to the shelves, the pole is not a "weak point". We had this type of corner susan in our old kitchen and it was the only cabinet that worked as well when we remodeled as the day we moved in 13 years before. It still turned smoothly and there were no issues with the shelves. That lazy susan held all our post & pans, colanders, and several oversize serving pieces.

Super Susan

• With a super susan, there is no pole, but you cannot attach the door to the rotating shelves b/c of the fixed shelves the rotating shelves are sitting on.

Comparison

• With the center pole in the lazy susan, you lose some horizontal space b/c the pole takes up space and you have to store things around the pole..
• With the super susan, you lose some vertical space b/c the combination of stationary + fixed shelves take up more vertical room than a single shelf in a lazy susan. In addition, the door cannot be attached to the shelves.

It's up to you which you prefer.

Blind Corner

FYI...the second picture you posted is a "blind corner". My MIL has that and she hates it! She doesn't have one of the swing outs so she just doesn't use the "blind" area. Those swing outs may look cook to some people, but if something falls off the inside the cabinet you have to send a small child inside to retrieve it b/f closing the swing out. (When my KD told me this, I was skeptical - until I saw one in action - she was right!)

Personally, I'd do:

1...cabinet turned 90 degrees to face outside the Kitchen (if possible)

2...corner susan -or- corner drawers

3...void out the corner

4...blind corner; actually, I'd rather have a voided corner than a blind corner, so I'm not even sure I would include it as an option!

The nice thing about a "lazy" susan with the center pole is that the door can be attached to the shelves and rotate in when opened (Kelleg69's picture). That eliminates the piano-hinge doors that can bang against cabinets on the side.

But not unless you are doing inset cabinets. So, if the ikea ones in the OP are the actual contenders, no can do, unfortunately.

"...not unless you are doing inset cabinets."

What? That's not true, I had one like Kelleg69 showed with partial overlay cabinets. You don't have to have inset.

Okay. I should have said not with full overlay cabinets like the ikea cabinets Annette Holbrook is using. Sorry, point taken.

You can't get them with full overlay? I wonder why not...they would work exactly the same. You just won't get the full overlay look at the corner - which may or may not look "right".

It's probably moot anyway since she's using IKEA and is limited to what IKEA offers.

I've had both and a void cabinet. The void just bothered me because I couldn't stand the wasted space. I needed it. Of the other two, I like the Super Susan. It just provides more storage space. I don't like the accordion door, however. It's fine for me, but I could see toddlers wanting to swing on the door.

My daughter has a smaller kitchen and she went with a blind in her kitchen because she wanted more drawers and the blind gave her room to store a couple of large items. She placed the items on large trays which she slides out from the blind. She stores her potatoes and onions in a couple of baskets that are easily removed to access the larger items in the blind. She stores an ice cream maker, crock pot and some baking pans that are not used often.

The blinds arrived with the top shelf as deep as the bottom shelf, which she had the installer cut back to 14 inches deep to make it easier to access the blind.

If you're into the math, I found this older post interesting and informative when I was deciding on a corner cabinet.

Corner Cabinet Space Calculations and Analysis

I was on my way to having a corner cabinet that opens to the back of the peninsula, like my old layout. Knowing how it was used before, and how it was used in the house I grew up in (which didn't even have an overhang getting in the way) I decided I'd rather take whatever storage a super susan could give me on the work side of the peninsula. In our torn out kitchen, that cabinet held a coffee roaster, deep fryer, and easy bake oven. 2of the 3 are out the door. The third will fit in our pantry and mixing bowls and measuring cups will likely take up residence in the newly accessible corner.

The super Susan or lazy susAn debate was solved for us when we got our cabinets off Craigslist. We took what was offered. The door is hinged in the middle, and we've tried it out in its future position next to the range and it worked out just fine.

I'm not sure what my corner system is called (magic shelf?) but I was adamant about not having a Lazy Susan. I think it's a great way to get at all the space, easily.

I have an ikea lazy susan corner cabinet. I found that Ikea's LS wasted a lot of space. I think they should have made them larger. Even the 42" blind corner cabinet contraption wastes a lot of cabinet space. We looked at the set-ups at the store that didn't have countertops on them. My second would have been shelves like pictured above, as well.

I ended up using (mrspetes pic) 2 32" Super Susan's. Fills the space better and along with that we added a lazy susan light to the side of the cabinet. A big plus to be able to see everything.
