I own those three, really can't go wrong with any of them. I'd say DI is my favorite of the three, but Maiden is very close behind that and Wonka very close behind that (kind of like an A+, A, A- type of thing). Any more parameters? Wonka is the most family friendly (the movie has lots of black humor, but the pin doesn't), Maiden is a great game but I think appreciating the band would go a long way, and DI is for hardcore pinheads/Lawlor fans. None of 'em have a straight forward rule set and they're all deep games, but there are enough obvious things to do that don't require studying a manual or Bowen/DeadFlip videos.

I'd ask my wife to rank 'em if she wasn't sleeping right now, but I'm sure she'd say Wonka #1, not sure how the other two would shake out. But she loves themes. If Iron Maiden was Great British Bake Off or Schitt's Creek themed instead, she'd probably play it 8 hours a day.
