I haven't ridden a ton of coasters, but here are a few of my favorites:
Phoenix at Knoebels. I like Twister, too, but Phoenix is great.
Expedition Everest at Disney World. That's another one I can ride again and again.
Space Mountain at Disneyland. The one at World is good, but Land's is better.
Intimidator 305 and Twisted Timbers are both extremely intense for me, I can ride them once per visit, and that's about it. They're both great coasters though.
I haven't tried Skyrush - the last time we were at Hersheypark, it kept breaking down, and then Covid, etc, so despite having family in the area, we haven't made it back. I also want to try Candymoniun. And they have a new Rocky Mountain conversion that just opened. I've heard good things.
