Raider - hyper? stealth? what's the difference?

So while searching for a Raider I came across a couple that are labeled “Hyper” and “Stealth” - are these actually any different than the normal Raider or just re-named? If they are different, how are they? If it makes a difference - I’m looking to modify for looping, I have one modded Raider and its my favorite looper…

Raider is the standard raider by Yomega.

The Hyper raider is also a standard raider that was rebranded and repackaged for the bandai/hyper yoyo promotions goin on in Japan during the late 90’s.
The Stealth raider is the “wing” shaped version of the raider which was a rebranded “saber raider” for hyper yoyo.
