I don't use a whole lot. I like the grenade laucnhers, about two machine guns, and a sniper gun. I don't use the handguns at all. Occasionally I will use sticky bombs or hand grenades, but they aren't too accurate. I like fast or distant weapons, since my reaction times aren't the fastest. I prefer war machines in most games I play, but the tank in GTA is pretty weak in my opinion.
