Current: Tron/TWD
90's: AFM/TOM
Sys 11: BOP
SS: Blackout
EM: Fireball
Nothing interesting about my list, except maybe Blackout as my SS choice. Not sure whether Fireball would be a keeper as I've never played one that worked particularly well.
The caveats are that I don't have the space, can play all of these at nearby locations (<2 miles from my house), and I don't presently care to own $30k worth of pinball machines.
