Which Stuff Packs do you think are worth buying?

Well, i do plan on getting them all, because i truly feel uncomfortable if i can't take the full advantage of all the things the game can offer me.
With that said, maybe it is true, maybe some Stuff Packs aren't worth the money (Do notice i'm brazilian, so the packs are actually more expensive than 10$ for me) but i really can't help it, once i'm able to, i'm getting them all.
