In my area moen products have the most problems out of the box, meaning that either they won't work upon install or something is defective.
I work on Delta faucets a great deal.....mostly because they are widely installed. If you have high water pressure you will be replacing parts on a Delta. If you are buying remedial rebuild parts on Delta, you'll constantly be replacing parts on them. It's all about using genuine quality Delta parts that make a good rebuild. Otherwise Danco is your part-time friend.
I do not like working on Moen faucets because of the effort it takes to pull the cartridges. If you have galvanized piping leading to a Moen faucet you'll be taking those pressure-temp cartridges apart daily to keep the balancing spool free moving.
Moen has Delta beat on looks/style/different kinds. I install a great deal of Moen faucets just because they are solely bought on looks, not functionality.
I won't install a american standard faucet, no matter what kind or style. Too many problems lately with that product and taints the customer-service provider relationship even though I didn't supply the faucet. Notorious for problems/operation issues.
Price Pfister is sold around here but many don't install them. I have no idea why but every once in a while I'll put one in.
Kohler, run away screaming like your shirt is on fire. A nightmare to deal with down the road. It doesn't really matter if they are made from 5 pounds of brass, I want nothing to do with them.
Pegasus (home depot store brand) look nice and are well constructed with numerous styles and finishes but everything to repair them involve a 1-800 number.
Danze is similar to Pegasus and Danze is considered high end like Grohe.
I've dealt with 3 grohe faucets in the past 3 months; high end product, good about sending parts under warranty just like Delta and Moen.
All 3 faucets I dealt with had problems with them directly caused by normal wear and tear so I can't say it was a defective product.
I install a great deal of LadyLux faucets, seem to be a common faucet installed in high end homes.
That's all I got. Me, I like Delta. Easy faucet I've seen to work/repair/install.
