NFS Shift or Forza3? Need help deciding

[GamerOhaLAA]

Okay. I've been looking forward to Forza 3's release since last month when I decided to step into the racing game scene. I love the forza 2 custom paintjob stuff and i guess they'll improve in that, so it helps my anticipation.

But, Need for speed Shift looks awesome too. I played the demo and all. I love the graphics and the feel of the driving in the game.

I dont know which one i should get now. I believe forza is a bigger game from what i read and hear, but NFS is stunning too. Which one should i buy and why. Which one will/would you get and why. HELP!!!!
