Sorry I didn't see your post before.
Actually, Thunderstorm feels and performs very similarly to Hyperion: very soft, comfortable and explosive. Maybe it's even more powerful. I'd still give the edge in control to Tornado.
It'd be something like this:
Tension stability: Tornado=Hyperion>Thunder
Spin: Tornado( in the very first hours )=>Hyperion> Thunder
