I just found the Top-100 page for EM: http://pinside.com/pinball/top-100/em
Was fascinated to see the current best one was a Zaccaria... Forza Italia!
then realized 8 of the top 10 "average" ratings are based on a single rating.
IPDB has more, but I guess we could and should do better on Pinside !
So please contribute!
