I only have ridden a measly two.
1: Shambhala - Love the openness of the trains and the expedition theme. Great floater airtime, not a very intense ride but I like that it has more to offer than just airtime hills, I love the inclusion of the spashdown element and the interaction with Dragon Kahn.
2: Silver Star - I honestly don't think there is a huge gap in quality here, Silver Star is a solid hyper coaster with some great airtime moments (especially the drop off the mid-course), I do agree that the airtime on the first few hills isn't as strong as Shambhala, it has always given me solid airtime throughout. I think for me it's the scenery which really gives the lead to Shambhala.
