Get sleeping dogs or beat GTA IV first?

I've got such a backlog of games right now but I always love getting new ones. I'm a big consumer whore for video games. Is sleeping dogs even worth it or am I better of finishing GTA? Phone Post

 If you haven't finished GTA in 5 years you're not going to finish it anytime soon.

Sleeping Dogs is more fun with way better graphics and way better gameplay mechanics (hand to hand combat in particular).

GTA has imo a much bigger, much more believable city. Plus you can fly helicopters.

 Only played the demo of Sleeping Dogs but found it far more enjoyable than dull, overrated GTA4.
