Which is better Battlefield 3 or MW3 and why?

MW3

Pros:

Played very competitively

Addicting

Easy to get into

Huge community

Large variety of customization and weapons

Very Multiplayer based.

Cons:

Rehash of MW2 (Not much of a new game)

Not very realistic

Has a reputation of being unbalanced in Multiplayer

You will want to rage quit games often

BF3

Pros:

Realistic in all aspects

Vehicles (Jets, tanks, armored cars)

Cutting Edge Graphics

Fluent Movement of your character

Destructible turfs (Some one hiding in a building? Blow it up.)

Long Campaign

Very objective based Multiplayer (Not all about getting highest kill to death ratio)

Cons:

Hard to get into (Getting used to bullet drop etc)

Not as easy to customize your weapons as in the Call of Duty series

(*Large Maps, if you don't like that sort of stuff because of people hiding everywhere)

Pretty much what everyone has said so far is true. Long story short, Battlefield is ultra realistic, and COD is nonstop action.

To be honest, I picked up BF3 on the advice of a friend who's crazy in to first person shooter games. He loves the realism of the game, and I don't blame him... graphics, realistic deaths, crazy explosions... they really paid attention to every little detail in that game and its pretty impressive.

But me personally, I traded in BF3 towards my purchase of Modern Warfare 3 after 5 days. Someone else here mentioned my biggest issue with BF3... the size of the maps. I can't tell you how annoying it was for me to run around this gigantic map for 30-60 seconds, get sniped by someone, and have to start all over again trying to find people.

In the end, being a casual gamer, I decided that if I'm only going to play a shooter online for an hour or 2 each night, I want to have fun doing it. COD provides that in droves. Nonstop, crazy action. Need to have quick reactions and be aware at every corner because people are usually popping out somewhere. Do stupid things happen in the game, like shooting someone 5 times and them running straight at you only to swipe a knife at you and kill you? Yeah, sometimes. But it's pretty rare and I would say that if there's a battle between 2 players shooting at each other, 90% of the time the more accurate and quick player wins the shootout. COD has also done a good job in MW3 with their maps... I've noticed much less "camping" from players than in MW2 and Black Ops.

Overall, I'm of the opinion that BF3 is for the super hardcore gamers, and COD is for the masses.

Modern Warfare 3 sees the return of the much loved spec ops mode. These mini games and challenges are highly addictive and push the Call of Duty gaming style to its adrenalin filled limit. We were lucky to get a play through survival mode, which is not unlike Gears of War 3's horde mode. Essentially you are tasked with defeating wave after wave of enemies, including juggernauts and yes...dogs. Not easy but incredibly rewarding.

Battlefield multiplayer pros: Fly in jets, pick your own maps.

Battlefield multiplayer cons: People use tanks ALL the time, maps are TOO big (run for the objective for 30-45 seconds, die and start back running another 30-45 seconds)

MW3 pros: Full gun customization, balanced guns, set up with perks of your choice for your preferences, and fast paced high action fun.

MW3 cons: People sit in one place and camp.

I have both and I still prefer CoD. I have all the battlefields and Call of Duties (Beaten all campaigns on hardest difficutly)

Depending on your play style, a person can make the opinion on which game is better.

BF3 is more tactical and patience driven rather than Mw3's action packed always moving gameplay.

I have Mw3 and I am glad I got it because I like the action and it's fun singleplayer.

i think MW3 is the best game in world

Battlefield 3 there's way more to do but that's just me.. Go on YouTube look at some gameplay footage of both and compare. good Luck!
