TSPP couch MB. It's very difficult to manage the lower PF while trying to make super jackpots on the upper PF.
WCS. It's simple, but it's satisfying to relight and nail those jackpot shots.
Worst
XMen weapon X. I probably wouldn't have thought of it if you hadn't mentioned it. It's just not that much fun, and the heavy panting is some of the oddest 'music' in pinball.
