You kind of can't lose with those IMHO. So in that sense you're in a good place.
I have a nicely modded Tron Pro and a Metallica LE, no AC/DC. So can't truly compare all 3. I've played AC/DC though.
I think I'd personally recommend Metallica Premium. I love Tron, it's a great game and I have a strong emotional connection to it, and it has that "one more play" thing going for it. It's a keeper for me. But Metallica has a lot of the same feel, but with more depth. The new Sparky magnet interaction is a lot like the disc on Tron. No upper flipper, but you get a better 1-2 combo on the ramps, and the left ramp shot feels a lot like the Quorra shot. There's just a lot more to shoot for and do on Metallica, with deeper rules. Sometimes you don't want that, and I love having both, but that's what gives it the nod.
AC/DC is obviously an awesome game, but I kind of like objectives in my games. Metallica isn't truly mode based, it's a scoring game with some of the AC/DC risk reward added into it (like in CIU cash in) but it has more discrete things to go for. You're not just setting up combos and stacks and points, though that's there, you're also getting more specific things. Like "I want to play Fade to Black CIU today". Gives you something to shoot for even if you're not having a monster game.
The Met Pro is good, but the extras on the Premium are totally worth it.
Also, Metallica gets the nod on art, even though I love Tron's look, especially with the lit ramps. But hand drawn art is rare these days. Daft Punk on Tron is great, especially with a sub, but I'd rather listen to Metallica than AC/DC. Those are personal call though.
