For anyone on the fence, I've been to most of the top amusement parks in America. Cedar Point is without a doubt the best of the bunch. You NYers who think Six Flags in Jackson is the ultimate park are in for a pleasant surprise.
Bear in mind, I have not been to CP since 06 and have been to SF a few times since then, and their rides are still not on par with CP. (Not to disparage SF, they do have some awesome rides, but it pales next to CP.)
And you gotta work harder on getting your wives on the rides. It took me a lot of convincing/manipulation to get my wife on her 1st major coaster (I think it was Nitro at SF) and now she can't get enough.
