If you want quick OTA updates then yes the Nexus is the way to go. If you are comfortable with installing leaks then go for the Rezound. The phone is more than capable of running ICS, JB and probably whatever comes after and as long as the leaks keep coming you can stay in the forefront.
My comments are my opinion and I could be way off....but logic and Verizon's history tells me I may not.
I have both. And neither has been fast to receive **** for OTA's.
