I like the streamlined look of the hansgrohe better than the lumpy look of the moen. I also prefer the water- going - out part flat rather than bubbled out. Neither look like the one in the pic though?
I prefer the look of the Hansgrohe. Trust me you can mix slightly modern styles in traditional rooms. Especially if you stick with a traditional finish like chrome.
PLUS the quality difference between those two is not even a close. If you ever taking apart a faucet or tried to fix one you will appreciate the solid metal machined parts. Like I can't even begin to explain it how much better it is in every way. You have to see it in person. And the Hansgrohe comes with a lifetime warranty. Same with Grohe.
