Thanks for all of the replys guys very helpful. But on paper what ones out of the high cycle series have the best gear box and motor and all that stuff. And ik the mp5k is not that unique but more unique then the m4 or ak. The p90 it's a hit or mis at the field wether it's unique and for the aug I was getting the high cycle version and I'm pretty sure it's pretty rare because it doesn't look like a normal aug I'll put link here for anyone curious:

Sorry for the big link and also the scorpion I hear is extremely well built and it outperforms a lot of aegs even though it's size is like a mp5k and its said that it has like the best trigger response for the price.
