Should I get the HTC Evo4G or the Blackberry Bold?

I've got an upgrade with Sprint coming in a few weeks, but don't know what I should get. I've narrowed it down to the Evo or the Blackberry Bold but don't know where to go from there. I'm a college student at Syracuse, and everyone has a Blackberry, but we also have 4G here and everyone loves the Android operating system. What do I do?
