As of right now, its kinda a 3 way tie between W, OOO and the currently ongoing Gavv, them all having really fun casts and engaging stories, along with each having cool gimmicks, they're all so damn cool

Well notes also say (excluding violet memory because that's like 9 years later irl time) he also appears in the 2010 kamen rider vs movie, where the second segment of it is technically the finale to his story (I think)

Oh I just remembered that Kamen rider Decade is only 31 eps and a movie

Yeah fair, sentais and riders go up weekly year round (how the fuck are they so consistent) but definitely would be interesting to see how these riders could clown on John whenever you have the time to get to them

Homelands vs Kamen rider Decade or Kamen rider Zi-o would be interesting
