World of Warcraft or Rift? Wich game should I play?

So I took a 5 month break from gaming. I came back and now I wanna know wich should I play? RIFT or WoW? I mostly love the pvp more then anything. There's nothing more I love then pvp. But I also love PvE. But not as much I love pvp. Wich game should I play? and why?
