No. As someone who has played the last few incarnations of the Battlefield series, premium hasn't really added much on the console version of BF3. Armored Kill is, like someone else mentioned, too large for the 24 player servers. Take Superiority is more of a "fun" mode than something I'd take seriously. Close Quarters, eh. I've had fun on the maps but it definitely is for the CoD crowd who prefer killstreaks and quick action as opposed to the normal BF style of play. The gunmaster mode is unoriginal and doesn't work as well as the original. Back to Karkand is probably the best expansion so far, and it's just the re-imagining of old maps in the BF3 format.
If I had a chance to do it over again, I would not get premium. Of course, I am bitter since I bought the game at launch and then bought premium, not realizing just a month or so later they offered the game AND premium on the cheap. Oh well.
