The AEK is a monster in this game. Heavy barrel and Angled grip. It has about the same spread as the M416 except with more recoil, which you can deal with. And the fire rate is significantly better. 750 for the M416 vs 900 for the AEK
The FAMAS is fickle. It complains and acts up constantly. But treat it right, and it's magic.
For those of you who are interested, the gun stats are laid out with pretty graphs and such at

Loving the game though, and the geo-leaderboards are really cool, comparing yourself to your town, state, etc.
Gotta say that Zavod 311, Operation Locker, and Flood Zone are my favorite maps so far. Paracel storm looks the best during that awesome storm.
Got banned for the first time in BF4 last night. Apparently my killrate was "too high" ><
