I have had all three.

Haunted House lasted the shortest. The music started to become tiring, and the game seemed to lack an overall purpose, despite all the playfields shots seem limited, slow, and without a multiball payoff bored me.

Spirit only just left the collection. Very challenging to achieve multiball modes, and a couple of really fun shots (especially the right flipper to top left saucer lock). I liked the game, but it never really inspired me, really don't know why. The four slings at the bottom do not appeal when they take over for extended periods! A good game, probably wouldn't have sold it but a collector was really keen for one and decided to let it go as it was not getting played at all.

Black Hole was the first System 80 for me and is due for a complete restoration this Winter, after that it will stay in its place. The complete SS package - lots of good shots, lots of targets, brilliantly implemented multiball, balanced scoring. Achieving a good multiball starting downstairs, then the switch to upstairs three ball is really well done rule wise. Despite the large window area creating an open playfield, the game does not feel like it has unused territory. Best of the three for me.
