How about that bunch of low cost highly effective WWII SMGs: The Soviet PPSh-41 and the Brit STEN gun ?
Then for finely manufactured ones the is the "Chicago Piano" - the "Chopper" - The Thompson. A favorite of the novels and movies, I found it to be heavy and very hard to fire on target. They still had a few in the US Army in the mid 1960s and I got to blow several mags through one.
For worst SMG, how about the Reising M-50 ? Hated by all US services
