The examples on the website are nice, however from what I saw, they can be done in Hype as well. As you mentioned, Hype is more mature and has a sizable community, many of whom contribute towards extending its functionality by creating custom modules in JS for things like dynamic data imported w/ JSON.
For 3D animation I've also used Spline, which is in beta. It's interesting, but on my 2014 MBP, it runs slowly and the fans are constantly on, which makes it less appealing for my use.
