Objective better versions and why;
>Gen 1:
Red version. (Or FireRed). Has the best exclusives, and it's the title name of the main protagonists.
>Gen 2
HeartGold. Whirl Islands make ZERO sense to be pre-Elite 4, actively harming the game. The Kimono girls even seem built for the Tin Tower story.
>Gen 3
Emerald, duh. (Between OR/AS, it's a tough pick. Aqua make more sense as villains I guess, but that only adds more fucking water to the game)
>Gen 4
Platinum, duh
>Gen 5
White and White 2 make much more sense thematically with N. The White Forest is much nicer than the empty Black city, and stops the game from having an overabundance of man-made locations. Even Generations acknowleged this.
>Gen 6
I picked X, but I think Y makes more sense with Lysandre's plan, and Generations acknowledged this by animating Y versions events.
>Gen 7
Sun has an almost flawless list of superior exclusives, and Moons fucked in-game clock during the main game is retarded. Solgaleo fits much nicer in the story too.
Prove me wrong. Pro-tip: You seriously, unironically can't.
