Favorite childhood series?

As a child, I grew up watching animated series like X-Men, Teenage Mutant Ninja Turtles, Gundam G, Yuyu Hakusho, Slam Dunk, Flame of Recca, Prince of Tennis, Voltes V and Daimos. On the other hand, some of the Sentai series like Masked Rider Black, Bioman, Machine Man, Turbo Rangers, I think they surpasses their American Counter parts. One of the example is Masked Rider Black, I watched the series from Japan which is the original, and I've watched the American variant which sucks big time, it even had a traverse scene with the Power Rangers which made me think what on earth am I watching?

I still watch anime series up to now and I'm stuck on watching One Piece which I think is one of the best animated series I've ever watched since I was a kid.
