G.I. Joe and Thundercats are better.
I'm not writing a hate post, but I cant help but feel Transformers is one of the weaker 80s action cartoons. I still enjoy it. Its fun, but its nowhere near the quality as G.I. or Thundercats. Even Ninja Turtles.
Joe and Thundercats have better animation, better and more cohesive stories and events. Re watching Transformers I'm shocked at how choppy it is not only in story, but animation as well. Its just not as well produced as other shows of that era. I still like it though. The characters are what keeps it from being a waste and it is rather fun to watch. But I'm a little shocked this is the reigning champ of 80s cartoons.
My rankings:
The Real Ghostbusters 10/10
Thundercats 10/10
G.I. Joe 9/10
Teenage Mutant Ninja Turtles 8/10
Transformers 7/10
