For me, it's:
1. Converse All Star - A classic. Even though every Joe Shmow wheres them, they have good reason to. They have comfort, durability, they are cheap (I'm poor ;;), and have a nice old school style to it.
2. Nike Air Force Ones - These just look really cool XD
3. Phat Farm Rev 1's - Comfortable, cheap show. They look alright, and they also have some pretty good durability.
