I have to say that the Loch Ness Monster at Busch Gardens Williamsburg is my favorite. It is an old but a good one. Also, if the ride operators time it right they can get both cars going through the loops at the same time.
Apollos Chariot is great for the out of seat hang time. The new one, Verbolten, was perhaps the smoothest launch coaster I have been on.
Volcano and Twilight Zone at Kings Dominion near Richmond were pretty good. I haven't been there for almost a decade. The last time I was Kings Dominion was kind of a dump. Hopefully, Cedar Fair cleaned it up.
