FAMAS was awesome, literally no recoil. AK was good too, but a new one I suggest trying is the AUG with Dual Mags.
I prestiged out on BO on my old account, so I feel somewhat informed when I say that the gun you choose is about as useful as the face tattoos in Black Ops. The perks are what defines Call of Duty and being able to find the combination that's right for the map/game mode.
Best class I ever had was
FAMAS Dual Mag - Although anyone worth their weight in dog piss at Black Ops knew that all of the assault rifles' stats were copy pasted with a little editing in the Rate of Fire department.
1911 Silencer - you don't use it, you kill until you find a good pickup and swap it out
Ghost Pro
SoH Pro
Hacker Pro - Some people prefer Ninja Pro, but as I wasn't a believer in Turtle Beaches at the time, I ran Hacker.
Frag - drop the semtex you noobs, once you learn to cook grenades effectively there's no comparison on which one is better
Concussion - Variety of reasons. much quicker throw, and if you are flashed you can throw a concussion and it'll disable the flash. Little glitch most people didn't pick up on...
Try that class out and let us know what you think. I can almost guarantee you that if you give it an hour or so, you won't go back.
edit in a side note: The only attachments worth anything are the suppressor and the Dual Mags. You don't need a sight on any of the guns considering the hardsights were awesome and LITERALLY uniform throughout all of the LMG/SMG/Assault Rifles.
