I personally wasn't the biggest fan of the series, but it definitely had an interesting villain in Megallen.
And random question, any idea why Juspion himself and Speilban look so alike?
I stole this segment from grnrngr.com :

Juspion and Speilban have a similar premise, so the suite design appears to be similar in the some way the Space Sheriffs share similarities.
