U.S. Vs. Japanese Cartoons

I guess this topic has probably been done to death here, and the answers can probably go on for days. Can someone give me just a quick breakdown, without any spoilers?
I was wondering which version is better, or which I should watch first, if I end up watching both. I don't mind subtitles too much if the story is much better in the Japanese versions.
Robots In Disguise(US) Vs. Car Robots (Japan)
Armada(US) Vs. Transformers: Micron Legend (Japan)
Energon(US) Vs. Transformers: Superlink (Japan)
Cybertron(US) Vs. TTransformers: Galaxy Force (Japan)
*I'm currently about half way through the US Armada, and have skimmed through several episodes of Robots In Disguise.
