I was going to ask this same question, and searched first (of course). I am renovating a 14 year old "white" kitchen and am now looking for a single lever stainless faucet.
Of the three brands mentioned, I have never had a problem with Delta, have always had a problem with Moen, and have mixed experiences with Pfister.
I see Mort and HJ have PFister on the top of their list. I I like the style of one of theirs and am considering it for that reason, but here is why I am hesitating. About 9 years ago I replaced the Moen (leaking, chipped finish) with a single handle Pfister with a white finish. The problem that I have is that the handle always seems a bit loose (it's not) and the finish is crappy (always dull, stains, crap grows on it, especially on the "ball"). I know that a lot of my problem is simply with the white, which is apparently an epoxy paint or something.
I also had a Pfister at my previous house. Again, no leaks or anything, just a feel of looseness on the handle that I coud never seem to adjust out. I like the solid feel of the Delta.
