What is the best option for a Verizon customer?

I have been with VZW for about ten years. I never had any problems but recently I have been thinking of going prepaid. Where I live in Florida, VZW is the only carrier with solid service. so now being stuck on VZW and without a new nexus option what is the best smart phone available? I have had the thunderbolt and now have the gnexus so battery is important. What do you think?
