Theres Back to Karkand which was good but I only really liked them on rush. Close Quarters was a good change of pace but is the same as COD but not as cramped and forced CQC. Armored Kill sucked because the maps were too big and there are not enough vehicles. From what I've seen of the newer maps they are good. It took me a while to learn them but they are a lot like the default medium sized maps like Seine, Bazaar, etc.
You can redownload the DLC from PSN for free if you had it before. I play BF3 a lot and I saw that Jim Morrison was on last night...my little brother plays sometimes, too. The Aftermath DLC is pretty good.
