I've tried to love it too, I really have. But the reality is with a super low ping it's not very playable at all. I thought the server browsers would be the answer, but they are not real server browsers on the PS3. Just a deceitful way of naming a screen that let's you choose which map you want to play.
Is MW3 any less laggy? Probably worst to be honest. But at least I don't have to run for 1 minute to get back to the action every time I die (which is far too often!). And it has special ops and private MP to lessen the frustration.
Oh, and did I mention how badly the BF3 controls suck?
