Should i get CoD4 or Battlefield Bad Company 2?

Dont tell me to get mw2. I think mw2 is absolutely frustrating. Maybe i will start playing it if Infinity Ward patches some stuff. But yeah. CoD4 or Battlefield Bad Company 2?|||i would get Bad company 2, because its relatively new. bad company 2 is like combining MW2 and the original Bad Company|||BBC:2.|||i dont know about battle field but i would get CoD4 becuz i could go online and pwn some asses!!!!!!!!!!XD
