One other component to your search you may want to consider is also the "breadth" of the pins rules/features. Meaning: how many meaningful things are available to attempt at any given time, which adds a lot of repeat play because of the myriad of combinations of stacks, sequences, and approaches you can take to the game.
I find that rulesets from Keefer and Lyman, as well as the designs/rulesets from Elwin have fantastic combinations of depth and breadth.
Dwight's rulesets also usually have great depth (Munsters excluded), and more recently, added variety from player-selectable path/character, but they don't have quite as much breadth as Keefer/Elwin/Lyman.
