I like "old" Cylone better than Superbe. I'm kind of the wrong person to comment as I do like "our-y stuff rather than race-y stuff. As I'm aware- 70s Cyclone is more versatile and lighter than Superbe- but Superbe is more robust. Not in a VGT sort of way- but more precise and dominant.
As you get into the 80s Superbe and Superbe Pro (sometimes "Superbe Pro" is a different line- sometimes it takes the place of "Superbe") were both racing and shoehorned into a couple of different long cage units.
pcb would have the better idea on this.
My personal favorite is the post 1989 Superbe Pro- I've read of them being referred to as "jewelry for your bike." The top level Suntour stuff was just awesome; the polishing and anodizing left them with that gorgeous sheen and shine. The shifters had that perfect twist to them. The hidden spring brakes were awesome- (the return springs were built inside the arms- so you never saw them).
One thing I totally love is the seat post- it's the most adjustable seat post- and it has that understated Superbe Pro branding. Which is precariously screened onto the post- one errant swipe and it's gone forever.

I sold off my brakes a while ago- someone got a good deal on those... I should get pix of the derailleurs. Beautiful stuff.
