I don't remember much of the OG Yu-Gi-Oh anime, I think I may even skipped some of them. So Yu-Gi-Oh GX has a much more fonder memory for me. I liked the academy setting quite a bit, and Elemental Heroes were pretty cool. Think I stopped for some reason before Neos came into play.
I did decide not to watch 5D's for years because of the Motorocycle concept. I only watched like 3 episodes, better than I thought but not sure if I should continue. I actually don't really understand the hate for Zexal, I don't like it as much as the original, GX, and probably 5D's and Arc-V, but it's not THAT bad. Too many niche decks though.
I did give the Arc-5 a try in japanese. It's pretty interesting. Still kinda off-put by the action duels, seems like a spin-off type of dueling like dice monsters, same with motorcycles. Idk these gimmicks are kinda annoying.
As for the decks I like to run, Spellcasters (Dark Magician or Gagaga), Morthtronics, or Batterymen.
