Which would you pick, and why? I'm up for an upgrade at the end of February, but I've decided to stay away from another contract. That said, I'm looking to spend $150-200 on a used phone. The two that I've come down to are the HTC ThunderBolt or Samsung Droid Charge. I've read numerous bad reviews on each, and on just about every site, the HTC TB has a better rating. But, I want honest user reviews, and not just "This phone sucks. Don't buy it!"
