Intamain Hypers provide alot of airtime, better than most steel sitdowns. But I think the king of airtime are Woodies, the bunny hopps get you out of your seat. It feels great, the lapbars really help! I also think Dive Machines provide a unique type of airtime, where you cant feel the seat or restraint.
I find most Disney rides themed well. My personal faviroute is BTMR, the effects are great... even when riding. Also I love Pirates of the Carribain, Disney done really well with the themeing and its a great experience.
At other parks I like Dueling Dragons, the queueline and the surrounds were done really well.
