Two of those three are modern day firearms, while the third, the M41, is from the movie Aliens.
Also, the P90 is basically a SMG while the M4 and M41 are Assault Rifles.
For sheer firepower... the M41A Pulse Rifle has a 99 round magazine with a built in under barrel grenade launcher. Hard to believe, but it is canon to Aliens.
The M4A1 is a versatile modern firearm that can be equipped with a wide range of attachments.
The P90 was made famous by the TV series Stargate SG-1.
"The meaning of victory is not to merely defeat your enemy but to destroy him, to completely eradicate him from living memory, to leave no remnant of his endeavours, to crush utterly his achievement and remove from all record his every trace of existence. From that defeat no enemy can ever recover. That is the meaning of victory."
-Lord Commander Solar Macharius
