I feel the reason people choose Dragster over Kingda Ka is because Dragster has a much better/intense launch. I rode both in a span of two weeks, and I liked Kingda Ka better. Dragster doesn't feel as tall because it is surrounded by water, so it kind of takes away from the height if that makes sense. Kingda Ka you feel like you are much higher than when riding Dragster, even though it is only 36 feet taller. Also kingda ka you tend to stay up high longer, while dragster tries to give you that airtime over the top, shortening the view. Both drops are the same. The hill on Kingda Ka lets you feel speed for a bit longer than Dragster does, once you are at the bottom of the tower you begin to brake, but you don't break until the hill is almost done. The hill has about as much airtime as Millennium Force (barely any). The good points of dragster is that it has better theming, looks better at night, and you have better viewing of it, but that is soon to change with Kingda Ka next year now that rolling thunder is gone. I don't really see why people complain about the restraints, not really a big deal on these rides. So it is usually up to preference. If you want better theming and better launch, go with Dragster, if you like more height and speed, Kingda Ka is your ride. I think people like Dragster because of that more intense launch, and it is slightly smoother. Both are absolutely incredible rides though.
