While the voice acting can be hit or miss, you may enjoy The Adventures of The Galaxy Rangers. It has a particularly awesome 80’s soundtrack and great visuals, and the plots are a bit more mature than the usual fare of that time.
Silverhawks is in a similar vain style wise, but it has more in common with Thundercats writing wise from what I recall of it (more juvenile), so adults may not get as much from it.
Megas XLR was a pretty good humorous take on the Mech genre from Toonami, and the whole series is on YouTube..




















No prob! Also, I found that Archive.org has the whole Galaxy Ranger series in much higher DVD quality compared to what’s on youtube.
