I'd vote Bluestar. If you have a choice between Thermador and Wolf, I'd go Thermador. I've had both. The Wolf continues to have oven paint chipping problems. Thermador has the superior shaped stovetop burner with that star-shape.

Wolf's problem, still occurring, is with the blue interiors on the wall ovens and DF range. The all gas range would be ok in that respect. Wolf does often have good service for the first two years when the appliances are under full warranty. Other times with the blue chipping they have somehow gotten people to invest more money in their product with the idea that maybe if you get a more expensive product, then it will work. There is a lawsuit now and the people after having several ranges replaced put more money in to upgrade from a 36" to a 48" range. After you pass the two years, you pay and you have to use their people. You are at their mercy as to what they want to charge you. They are unfailing polite though.

Thanks. I am not going for the DF range. I am surprised to hear you say that about the customer service wekick...that's the first time I've heard that about Wolf.

I do like the Thermador burners homechef59, it seems like it is much easier to keep the stovetop clean since they are raised.

We bought "Wolf" with idea of their supposed great service and have been very disappointed with the quality of the product and the failure of Wolf to stand behind their products.

What was wrong with your Wolf?

Blue chipping.

I've had both, but duel fuel. I prefer the Thermador. I like the low simmer and star shaped burners. The larger oven preheats much faster. Also prefer the removable and nonstick griddle, but I don't think that applies to the all gas models. Honestly, I think you will be happy with whichever you choose.

The all-gas ranges tend to be less problem-prone than dual fuel ranges, regardless of brand. They're simpler machine with less to go wrong. That's not to say you can be 100% confident that with an all-gas range nothing will break. It's just that the likelihood is smaller.

I like the star-shaped burners on the Thermador better. I haven't liked the Wolf burners since they changed their design of the dual stack burner a few years ago.

Any chance you can do a separate rangetop and a wall oven?

M Miller, I wish I had enough room, but sadly I do not. That's why I am going with 30" rather than 36". (I could do 36" but that would leave me with very little counter space on that wall. I will try to upload a picture of my current kitchen.)

Thermador has a 30 in 5 burner range that's pretty nice.ALL GAS RANGE PRG305PH

Here is my current kitchen

As you can see, if I put a 36" range here, I would have very little counter space. Does anyone disagree? My contractor told me to just go for 36", he said I will be much happier since I love to cook and entertain.

Just regarding Jakvis' comment about 5 burners on a 30" range...I am not a fan. What happens with that configuration is that there is a large center burner with 4 surrounding smaller burners. You get less utility than with 4 burners, because when you have a pot/pan on the center burner, the other four then only have room for a smaller pot/pan. Don't take my word for it. Go to a store that has it on display (or any 5-burner 30" range on display), and bring with you your 2 most-used pot and/or pans. Set one on the center burner, and set the other on one of the other 4 burners. You will see what I mean. Better to have 4 burners in the standard configuration for a 30" range.

For the question of 30" vs. 36" - first ask yourself how often have you used all 4 burners at once of your range currently. Most people do not use all 4, but do like the landing space of a 36" burner range. Second, keep in mind that not only do you forego 6" of counter with a 36" range, but also 6" of upper cabinet space. You will need a hood that is 36" wide over a 36" range. You cannot have a 30" hood over a 36" range.

P.S. I am assuming you are replacing the OTR MW with a hood. If you are not, then you must choose a less powerful range than the Wolf or Thermador. Either of those brand ranges are too powerful for an OTR MW, and would melt the underside of the MW.

Adding emphasis to what friedajune said, consider these points.

First, the large oven in a 36" range takes significantly longer to fully preheat than one in a 30" range.

Second, it will dump more heat into your kitchen while operating, particularly in convection modes.

Third, a 36" Thermador or Wolf range is much more expensive than 30" range. For example, scanning AJMadsion's listings, I see that 36" Thermador models cost from $1700 up to $2500 more than the 30" models. That does not count add-ins for the extra ventilation costs.

Fourth, will you often need five or six burners going at once to make all that extra expense worth the inconvenient loss of counter and cabinet space?

If the extra two burners would be only an occasional convenience, then it will be worthwhile to consider some much more flexible and much less expensive alternatives for those times when more burners might be used. For example, consider getting a 120v portable induction cooktop (PIC). Good 120v PICs can be had for less than $100, such as this one. Even a high-end PIC, such as the Vollrath Mirage Pro, costs only a fraction of the price difference between a 30" and a 36" range. Easily stored out of the way when you do not need it and can be placed for use elsewhere, too, which may be handy when the kitchen is crowded at holiday seasons.

If your contractor is thinking you might want the 36" range with a griddle setup --- say, for pancakes and such -- consider instead a separate griddle. Separate ones will be significantly larger and easier to clean than the ones on 36" ranges, and can be stashed out of the way when not in use. For example, you could look at a non-stick electric griddle such as the Broil King (around $100 and highly recommended by Cooks Illustrated).

The kitchen in my house is smaller than yours and I prefer a stove-top griddle that can sit on my gas stove under my range hood when I want to use a big griddle and stashes out of the way when I'm not using it. For that, I recommend looking at this stove top model by Demeyere (around $120). I've found it does an excellent job of straddling two gas burners without hotspots, It is very heat efficient (which mean less waste heat to deal with and maybe eases the burden on your OTR MW if your are keeping it. Plus, the polished steel of the Demeyere cleans up very easily even when doing messy things like burgers.

So, lots of additional reasons to stick with the 30" range size.

For venting over a pro-style range, I'm going to disagree a bit with friedajune on worrying about melting an OTR over a 30" pro-style range (unless your contractor hangs the OTR way, way too low.) No disagreement over not using an OTR over a 36" range but for a 30" range you might find these threads from 5
years ago helpful to thinking through what you want to do:

This is great feedback, thank you all! I think I will stick with 30", as I originally planned. You all raise some valid points. The microwave will be a slider in the island, we are putting a decorative molding with vent insert over the range. Good point about taking away from the upper cabinet space, that never crossed my mind.
