This is likely not completely fair as I have not been to a Busch Park, but among the others, I would have to say I like Premier (Six Flags) parks. That may be biased as a SF park (GAm) was my home park, but I have been to CP (CF). PC, PCW, PKD, PKI (Paramount). Disneyland & MK. and SFA, SStL, SFoG, SFGAm. The SF parks seem to have a nice mixture of big thrills, flat rides, and decent shows. Lately though, the parks are all becoming mirror images of each other. And they are lacking dark rides. But their ride collection, combined with the sheer number of parks they have (all accessible by the same season pass) make them my personal fav.
