From the pictures I've seen, and after messing around with it in stores, the Rezound is bulky. The Nexus looks so much more sleek and thin.
If you're in it for form factor, Nexus wins IMO.

— bulk·i·ly This phone is not massive. It's thicker than a RAZR. The RAZR is not ergonomic. The Rezound is. I feel like people are assuming that thin is better when it is not necessarily so. The Samsung Charge, the Bionic the Revolution are all equally as "bulky" but because the RAZR everyone has redefined what "bulky" is.
