The only one I really like is Black Hole because it's possible to drain in the lower playfield and lose your ball. (granted there are some scoring imbalances and such, but the layout is solid and having to open the gate for reentry is brilliant)
If you don't have to worry about losing your ball if you play poorly in an upper/lower playfield, then why would you do anything else but play in the upper/lower playfield? Once you start to focus only on that small area, the game feels boring because there's not a lot you can do in the small area.
Also some are just objectively boring. ACDC is such a boring lower playfield. I'm sure the Munsters will get old, but it won't get as old as fast as ACDC.
