I get the feeling the JW coaster for Beijing will be more of a relaxing flight around the mountains and aviary than a thrill ride. Which is great, I think we need more rides like that. Velocicoaster will be more heavy on thrills but lighter on theming. So, might be a matter of opinion on which is better...
In either case, it's great to see two new attractions being built at the same time in two different parks rather than clones.
