World of Warcraft bows or guns which is better

For the most part this is a personal preference and somewhat depends on your class. Currently guns are more powerfull and offer slightly more stats at higher levels and are good for hunters and any other class that can use em. But they are loud, very loud.

Bows are quieter (crossbows too), but are better served in the ranged slot of warriors and rogues where they are used for pulling only. The stats are usually full of agility.
