There was a Delta pull-out in our house when we bought it. It functioned fine but I disliked the awkwardness of using it. Something about the way you had to hold it to use it in certain situations bothered me. The handle was just clumsy feeling sometimes. If I wanted to turn the head or clean the sink and turn my hand, the handle got in the way of the hose, etc. When we renovated we replaced it with a Kohler Vinnata pull-down. I much prefer the pull-down. It's just a natural, more ergonomically correct way of using a faucet in my opinion. I like that you grip the whole head of the faucet with your whole hand and that's it...no handle to fiddle with also. And no, if the faucet is made correctly, they don't dangle. We've had ours for six years now. It retracts perfectly, doesn't tangle and always goes back in just fine. What Frankoma states above about a pullout, stands for a pull-down also. I can fill my coffeepot or my stockpot on the counter with my pull-down just fine. It doesn't just pull DOWN, you pull it down and out too. :)

Personally, I like the looks of my Kohler bathroom faucet way better than my Grohe kitchen faucet, but I would never, ever want to use my bathroom faucet in the kitchen and I have a relatively huge bathroom faucet (a Kohler Purist tall -- with a non-vessel sink). You also have to consider scale and functionality. The faucet should look in scale with the sink. Bathroom faucets are usually in scale with ~20" sinks. Kitchen sinks are 50% bigger so kitchen faucets are bigger. Yes, some are ridiculously bigger, but most are just 'in-scale' bigger. Almost all kitchen faucets have a longer reach than bathroom faucets. You need that to get pots and such under the faucet and for good rinsing. Sure, you can get around that by having a separate spray, but that would be a pain to have to fill up your pots with a sprayer, huh? I guess, kinda like that commercial, you can take your bathroom faucet to a kitchen designer and say 'build my kitchen around this' and see what you get.

i hope you get responses soon as I am having a similar situation with an 8x8'2 bathroom where I also want to include my washer/dryer stacked or unstacked, stacked will give me space to add a cabinet for towels etc.

I use my pull-out laundry faucet every day. Makes rinsing out the laundry tub easy. Mine isn't Moen, but Moen is a good brand.
