The Uzi is useless compared to the P90. The MP5k is good, but I use silencers, and it suffers a lot from the range reduction since it has the biggest gap between min and max damage (40-20, while others are 30-20 (Uzi/P90), 40-35 (UMP), and 25-20 (Vector)). For me it is kind of a toss up between the P90, UMP and Vector. When it comes to getting the kill, I would take the Vector for its low recoil and beastly ROF. However, it runs out of ammo very fast, which is why the UMP and P90 are in the running. The UMP is a 3 shot kill at any range without Stopping Power, which is nice at medium and long range, but it is pretty mediocre for close range, and the recoil definitely hurts it at medium and long range. The P90's big magazine is very nice, but it is the worst of the three in terms of how long it takes to kill in medium and long range combat. I am going to be using them a lot for the next few days. Hopefully then I can have a more definitive answer for you. :p
