The p90 is better because it's magazine size is much bigger (50), compared to the mp5 which only has 30. Also the p90 has a faster rate of fire.
You would have to define better. There are different firearm models for different needs, and there will always be a difference of opinion on firearms.
yes in the first level that was unveiled at e3 an enemy dropped a p90
M16 Red Dot | P90 Silincer
The best fun is p90 with silencer
Well, I would recommend using the P90 or MP7 weapon, in my opinion they are great guns.
guns on call of duty modern warfare 2 are M4A1, ACR, FAL, SCAR-H,TAR-21,AK47, MP5K,UMP45,P90,MINI UZI, INTERVENTION.WA200,RPD, AND MANY MORE
all i can tell you is to watch the trailer and the gameplay from e3 and you could see maybe various types of guns. but if you do trailer try and relate to ones you actually know. as far as i see it there is, - famas -p90 -ak47 -m4a1 -mp5 -barret 50. cal - and some other sniper rifles and machine guns

God only knows, I hope the P90 :) is in there, um..... MP5 maybe, i don't know it's quite impossible to tell what is going to be in Call of Duty Modern Warfare 2 but it sounds great and....... instead of a 7 kill streak for a heli its a 10 kill streak for a laser (i think) ??? well i dnt know exactly what the guns are called but if you go on youtube and look up cod 6 weapons and perks you'll find out what some of the weapons are and i think two really good perks
G36c holographic and silencer. The best gun on my oppinion is the p90 with the silencer and rapid fire or acog scope and silencer.Its a pretty quick reload to.
ump45 is better by far and when it has silencer it rules
