The P90 is good, but i wanna try out that mp-7, that thing is tiny. Thompson was good for its time but nothing compared to modern smg's like the mp5 series, p90, ump, in fact id say the ump is more of an equivilent to the thompson. P90 is a good weapon if you shoot at kevlar wearing soldiers in your spare time. Another thing why is the colt "commando" (m4 veriant with short barrel) classified as an smg? it fires 5.56mm.
The MP5 is probably the worlds best anti terrorist / SWAT weapon in use today. This gun is so reliable and accurate. I can hit a reactive metal target at 75 yards over and over again without any recoil what so ever. Threw iron sites. ( can't see the laser pointer at that range during the day )
im not a big gun expert (not at all), but I read a few weeks ago in the paper of a gun named Tabur or Tambur (in hebrew) that was developed by the Israel Army, and was found to be better than the M4
now is the M4 considered to be better than the MP5 cause im really cluless about the whole issue
