I had the Rezound for 6 months and was never really happy with it. After 6 months of poor customer support and quirky phones, I gave up. I hadn't considered the Razr when I originally got the Rezound because I like extended batteries. When I went to find a new phone I narrowed it down to the Droid 4, Nexus and Razr Maxx. In my opinion the Razr Maxx won hands down.
I've had it for a few days now and already like it a bunch.
