There really aren't any bad choices there...
Maiden is AWESOME if you like or can at least tolerate the music. Same for Metallica but it's kind of more generic and brutal, and it's a DMD based title so you lose the cool LCDness.
SW has a TERRIBLE plunge, maybe the worst in pinball, but it really fun when you get control, plus who doesn't like SW?
If you don't like SW, but you do like The Walking Dead, it also has a somewhat unfortunate plunge, and also needs a sound mod to bring it inline with the TV show.
GB is great to some, poison to others. I like it personally.
Going outside the box, the best choice MIGHT be Guardians of the Galaxy... great theme, new display, Metallica-ish PF but a super cool ruleset. Still needs a sound mod tho, lol.
