I've played a decent amount of both and Paintball is defiantly more fun to me, but a lot more expensive. Airsoft you can just waste ammo and it wont cost you a dime. it's like $8 for 5,000 BB's. But i love paintball more because it's more close quarters (at least for me) and it doesn't hurt as much (to me). I prefer a solid "Smack" compared to stinging. And it's a lot more satisfying when you nail someone because you can actually hear the ball hit. But on the other hand in airsoft you can have a lot more people because it's cheaper, and it's always fun to sneak up behind someone and pop them in the back of the head. That's just my opinion, though.
