Imperfections and subjectivity of a pin ranking list will persist even with a tweak like enforcing a delay period before a pin can be rated. The EM list is also very subjective and often doesn’t seem to make sense. E.g., 4-player Gottlieb “300” is currently ranked 146, but the 2-player version “Top Score” is ranked 85, even though the only difference between them is a slight difference in the backglass artwork. Then there’s the ranking of Hot Tip, my favorite EM I have ever played, at 132, which has even dropped a spot since a recent thread discussing its low ranking.
Pinsiders prefer different eras, different sounds, different levels of complexity, even in EMs decades after they were released. That’s the case for all pins, like the Pinbot vs. TS4 comparison.
