It can depend on a few factors such as who, if anyone, plays with you and what type of player are you?
Having significant time on all three, I feel AC/DC by a long shot. It has the "Just one more game factor". I've barely touched any of my other games for the last 2 months. Not only that, but it has a tendency to draw people to it. Although it's a difficult game, lesser experienced players don't seem to be intimidated by it and it's fun! Don't worry if you're not an AC/DC fan, this pin stands on it's own legs.
On the other hand, TZ is a great game, but it does tire after a while. If you had to complete some modes, instead of just starting them, to get to LITZ, it would be a better game. It is VERY intimidating to lesser experienced players. My girlfriend won't touch it.
Transformers, to me, just felt like a grind to play. It just seems like you really had to work to build up some points and the modes were kind of the same (it's been a few months since I played it). A lot of players seem to complain about the code. I think it would also help if you were a Transformers fan.
Good luck!
