During the NW Pinball show there were eight (?) BK games, one AC. There was always 1-3 deep players on BK, always 3+ deep on AC.
Before it got all noisy (the night of the 30th) I got to play quite a bit of AC, and the music and sounds were killer. Graphics also. Matched the same art/design of the BG and cabinet.
I did come there with the intention of playing AC and a few other newer titles among other things, and I heard some bad press from some of my buddies about BK... I wouldn't refuse either, and since I have a smaller chance of obtaining an AC (money, only 500 made etc.) I'll probably get a BK at some point in the future, but if I had to choose now, AC would be my go-to.
I've never been an AC fan (music), but the guy is quite the showman, impressed he's stayed in the music business as long as he has.
I'd even go so far to say as I liked AC over Octoberfest, Houdini, remake Monster Bash, remake Attack from Mars, JJ Pirates, Beatles.
I did have a hell of a good time playing BK and Iron Maiden and Deadpool, also. It would be tough to choose between those and ACNC. Munsters was fun but not for me.
