All I can say is that in regard to any plumbing needs in my house, Delta will always be my first and only choice. When I turn my tap to "off," it goes off. I never have to force it. And when it needs fixing, I as a regular home owner can fix it. That's what I just did to the faucet in my kitchen (Delta 9192-AR-DST). So for me, it's ease of use, ease of repair. I'm sticking with Delta. (And Oh, that life-time warranty! The icing on the cake!)
