Most of the SMGs are outclassed by others, for instance, you have no reason to choose MP5K over AK-74u, or Uzi over anything.

This also happens in assault rifles, where basically if you don't pick Famas or AUG you're gonna have a lower hand (sometimes Galil, Commando and AK-47 can compete but they're still worse).

Thankfully all LMGs and shotguns are usable (to an extent), although M60 seems to take the title for the best LMG.

As for sniper rifles, you can follow this simple rule; take the PSG-1. Dragunov and WA2000 suck, and L96A1 is good (and fun) but still inferior.

And of course, Python and CZ75 rule the pistol category, and China Lake is at the bottom of the launchers.
