P90 vs M69 in MM

Alright i am planing to get a gun to be used in mm and maybe gm if my xm1014 gets old. i will get ammo packs for these guns so it sees that the p90 will get the extra clip and the m60 wont and i haven't checked for the mp5.
i don't want case guns.
my list:
P90
M60
mp5-avd(only if its better it then the other 2).

P90=(PROS)
has a FAST rof good clip size and is light (CONS) has "slow" reload and is kinda weak cant really 1 shot. (why does everyone say its slow its just as fast as the sig552 na d its not "slow")

M60= (PROS)
huge clip ,good damage can 1 shot really good over the p90 and has a good rof, (CONS) really heavy and has slow reload.


MP5-AVD=
a gun that i know is good overall but maybe not in mm
