Best TF shows like Prime?

[GC Brad]

Hey folks!

Just started watching TF: Prime recently and it's great. The wife has been enjoying it as well (we also liked Earthspark) and it seems to me the common denominator here is character development and ongoing storylines.

I'm not mega-familiar with all of the various TF shows over the years, what else would you recommend that has the same sort of character/plot vibe as the above?

B e a s t W a r s (but you already knew that)
Other than that, uh, Rescue Bots? Transformers hasn't really had a lot of great, well-written, character-driven shows.

Huh! I hadn't considered Rescue Bots... I'll add it to the list!
