World of Warcraft or Guild Wars?

Def World of Warcraft. SO many ppl leave Guild Wars for WoW... and many of my friends that play WoW stopped playing for a while so they could try out Guild Wars... they got their char to max lvl and came back to WoW. They said Guild Wars blows. WoW never ends and there's more to do ;) Anyways... WoW ftw!
