I have LE versions of both. Met ruleset is much more aligned with my preferences. I like modes that open up as the game progresses. Met has that in spades. ACDC allows you to pick any mode you want and go at it. The only progression to work towards is Encore. ACDC has interesting risk/reward tied to building up bonus, but I don't find that terribly compelling. I get much more satisfaction from opening up a Crank-it-up mode on Met, or starting Justice, or Seek and Destroy, etc.. etc...
