NowGamer has played the multiplayer of BF3 and MW3 to death and has compared both in this article.T hey've also been playing the beta all morning, and talked a bit about it too.

Battlefield 3's former Lead Designer has revealed that there were two cut missions from the main campaign
Get rid of campaigns, move the game to mobile, and try to compete with warzone. They would save time and money.

Players are using hacks to gain an advantage in the game, such as aimbots and wall hacks. The first gives a player superhuman aiming abilities, while a wall hack lets you see through walls to gauge where other players are.
“These hacks are typically used by PC players, but those playing on PC via Xbox Game Pass are identified as Xbox players in multiplayer lobbies.”
This is pretty dumb to say the least.
Don't Gamepass online games have anti-cheat systems?
If not, that's pretty dumb. Microsoft need to fix that asap.
I mean, COD games was always filled with hackers, nothing new. I can’t blame MS on this. Activision had years to try and fix this. Might take MS some time to make some change.
Very different games going after the same market? Is this like the old PES vs FIFA battles? FIFA's simulation style won out in the end and BF3 has a real simulation feel to it...
what a cop out, i read that whole thing simply because I wanted to see what he thought better, and then he takes the wussy route and says, " it depends on your style of gameplay, you choose". Well I say man up and be real about which one is better, even if its your opinion, you let your credibility go right out the door when you decided to hold back your true sentiments about these games. Booo!
i dont care about any comparison between the two!!
for me, both are different games and i AM buying both day 1..
F**k COD, that's my personal opinion I played the BF3 beta yesterday and strait away I was impressed with everything, the way each gun feels differant the sound is amazing and not fogetting people this IS just a beta and I personally feel that the metro map (although really gd) has very limited destruction which makes me wonder why people slated it buy saying the destruction part of the game is petty lame I generally think people are going to be eating there words once they have the full copy. I dont know but I think we have only seen a small fraction of what BF3 is capable of and I think dice know this.
"In all seriousness, the speed is almost on par with the Call of Duty series now, but this is by no means an attempt to copy Activision’s franchise"
So BF1942 speed then - finally!
