Moen is easier to find replacement parts for, but all plumbers love Delta and Kohler.

I thought I should add, both of these have lifetime warranties.

That is a given with a decent brand. But, ask hour plumber which brand he prefers, and why. Support under that warranty, and available parts are big reasons why the people that have to install them have favorites.

Both very nice. I went with a similar Kohler Artifacts faucet and have been very happy. Good quality, pulldown faucet has a heavy duty hose with a large weight that give it good action when using and it locks into place nicely. Very easy installation.
