PP90 has a faster time to kill if you hit all bullets, it has a better hipfire and is better close range. It does NOT have a better accuracy! The MP7 however is better overall, it can hit longshots across the map, great iron sights (goes for the pp90 as well), less muzzle flash when shooting which helps in long range firefights.. Basically the PP90 is the best gun in the game when it comes to short range, the MP7 is a combination between an SMG and an Assault rifle, it´s not the best long range, not the best at short range, but it is better than average at everything. You can use it on any map in any situation, that´s why a lot of people prefer it. I use both, and depending on the situation I´ll pick one of them. I don´t think one is better than the other, they are just different.

the mp7 beats the pp90 hands down in my opinion but the p90 can beat both of them

The MP7 is ridiculously accurate. Try killing someone using a MP7 from a long distance with the PP90. It's a lose lose situation most of the time. Although the PP90 will beat the MP7 in a face to face battle. Well through my experience anyways. I just love using the PP90 to clear rooms. The P90 is my favorite. I don't use any attachments, and like I do with all SMG's, I use range. But the PP90 is my most used SMG. I use range and extended mags. The MP7 I use range and rapid fire.

Mp7 is easier to control & has less no noticable muzzle flash than the pp90 especially with rf, which sucks mid range. Pp90 is king cqb and takes a hit outside it's zone needing 6 hits to kill at best, compared to 5 on the mp7 with better accuracy / precision, though the pp90 does have better max damage range. Mp7 is a more rounded gun and easier to use all-round. Arguably more effective mid range and especially on ar range, while still being very good cqb.

I've been using it almost constantly on the presigue I'm currently working through. I put range and an AGOC on it and was headshotting from the church down to the lower building on Mission! I took out snipers from their nest with it before they could sight and hit me!

Yeah, it's OP... but that's why I'm using it. When there is something that is effective and you don't use it, then you are just putting yourself at a disadvantage.

The PP90 was the first gun that i got gold, and i think i have more kills with it that most other guns, i normally use silencer and ext mags with it..
