I have not had an HTC phone, so may not be interested in my opinion. I agonized over the decision of whether to get the Razr, Rezound or the GNex and went to multiple VZW stores to play with each phone.
I ended up choosing the GNex primarily for its HD AMOLED screen and the feel of the phone in my hand. ICS and the easy to unlock bootloader/easy to root and developer support were bonuses.
The reason I didn't pick the Rezound was because it is thick and didn't feel good in my small hands. It is also heavy and I don't like heavy phones as they weigh down my purse, which is already heavy since it is overloaded to begin with.
As for the Rezound screen, it was too washed out for my tastes. Yes it is more realistic, but I like the overly saturated colors of the AMOLED screen. The Rezound also has a very reflective glass screen. Outside the Rezound screen is unviewable - it is like a mirror. That was the dealbreaker for me. I need to be able to see my phone screen outside in bright light and you can't with the Rezound and you can with the GNex.
