Smart Phones

I am now officially in the market for a smart phone. I have it narrowed down to 5. Which, I know. LOL I've read reviews and talked to the guy in the store about the various pros & cons of each, but I was wondering if any of you folks have any experience with any of the following:

LG Ally

Droid 2

LG Revolution

HTC Thunderbolt

Droid Charge (Samsung)

Thanks! :-)
