I honestly think Cedar Point has the best line up, at least out of the parks I've done. Millennium Force, Maverick, and Top Thrill Dragster are all in my Top Ten; they're world class. Beyond that, the supporting lineup is still very good. You got 4 solid B&Ms, with Gatekeeper and Valravn being the stand outs for me. Gemini is a fun, smooth racer that actually has some pretty good airtime, and I can't really think of any other ride where you can literally high five the other train. Wicked Twister and Blue Streak are good, quick filler coasters. I actually think Magnum XL-200 is pretty meh, but others seem to like it more than I do. Mean Streak is **** but it's getting scrapped and likely replaced by something far better. That's 10 good coasters for me (technically 11 since Gemini is two creds
).
As for other parks that I've been to, Hersheypark comes to mind, with the three Intamins standing tall and Lightning Racer, Great Bear, Looper, and Comet acting as solid supporting entries.
SFGAd is another solid choice I guess. I'd probably rate it higher only if I got to do Toro.
Then you got other parks like SFNE that have two fantastic coasters, but lacks the good lineup of supporting coasters. Well, Batman is enjoyable, and I guess that S&S thing will help, but other than that, you're not looking at much.
SFNE's lineup would actually be more impressive if it had less coasters, like Kentucky Kingdom is right now with Storm Chaser and Lightning Run, despite the park only having 5 creds.
