Boy troubles... Which one would you choose?

I know these three guys who I've liked for the past few days.

They all don't know each other and they've all asked me out...

I've told them all that I'd think about it.

Which one would you choose?

Guy 1: has jet black hair and looked a bit like Harry Potter. He has glasses and plays percusion. He's one year older than me. Nice & really smart...

Guy 2: has blonde-ish hair, super sporty. Smart and always joking around. really funny. Hangs around and flirts with A LOT of girls...

same age

Guy 3: has light brown hair. smiles a lot, not sporty. smart. really nice, plays piano. was best friends with him in grade 4. same age.

I know someone is going to say "Just listen to your heart, blah di blah..." but I don't want to hear that, I just want some advice on what I should tell the two that I'm saying no to and also who you would choose...

Thank you :D
