I'm a Price Pfister guy, for what it's worth (I'm not a plumber but a general contractor, so its prolly worth a little less than some of these other opinions). I think that at their price point, they're very good. I don't think they're the best you can buy, but that comes at a price.
I also like Delta in general. Not a fan of Kohler, kind of neutral about Moen. Never used Grohe or Danze, though I've been tempted a few times to try one out. I'd avoid the kingston brass, as mentioned above, as how will you get parts? You want those to be readily available locally... though its nice that some brands (such as Moen) will send free parts, do you really want to be w/o a faucet for a week while you wait for them?
