It all depends on personal preference, if you like fully automatic weapons, then the M4 carbine or AK47 are decent. However if you dont mind semi automatics, then the G3 and M16 are just as effective when used properly. Remember: any gun can be effective when put in the right hands! even guns that seem weak like the Skorpion or M9 pistols.
