Should I get the htc thunderbolt or the blackberry bold 9300?

I need a good and reliable phone for 2 years that will keep me entertained and amused. I am 15 years old. A lot of kids at my school have bbs and rave about them. My dad has a droid and it seems cool but people have said that the bb is better than android and visa avers. I am an Internet and text person only and I like to be able to do some media stuff on my phone. Thanks and help me please decide.
