I have never done an actual list of the 30 William's System 11 machines in any kind of order (yes 30 - I missed a couple on my first count somewhere along the line) but here is what I would call the best & worst.
Of the machines I have owned or played the group I would call the best are:
Pin-Bot (my favorite machine), Whirlwind, Banzai Run, High Speed, and Taxi.
F-14, Black Knight 2000, Earthshaker, & Mousin Around running close second tier.
In the middle would be Diner, Mousin Around, Rollergames (doesn't get much love but a fun game), Grand Lizard, and Space Station
Just above the bottom would be Bally Game Show, Pool Sharks, Fire, and Police Force
On the bottom would be Bugs Birthday Ball, Millionaire, Bad Cats (kind of neat in its own way), Road Kings & Jokerz.
And as far as the other 6 or 7 I have not played them enough to decide.
