I've been very happy with most of the higher end Price Pfister faucets in general (kit sink, lav, shower). Try to avoid the box store models of pretty much all brands, they actually are different (use more plastic parts rather than the brass in the better ones).
Many plumbers tend to rely on Delta. I've not used a lot of their professional products (mostly worked with their Home Cheapo line), so I can't comment too much. My experience with their box store line has been mixed, not great.
Kohler is great if you're a designer. Some of their products are nice, some not so great. Its a mixed bag. If you want a pedestal sink or something like that, they usually have good quality, nice design in their china, but I don't particularly care for their actual plumbing fixtures, at least not at the price point.
All of this is from a general contractor, not a specific plumber, for whatever that's worth.
