Which game had the best post game content?

[Sheep]

Out of all available main series games, which one do you feel had the best post game content? What did you like about it? (Optional) Which had the worst post game content to you?

 

[Devalue]

Best: Gold/Silver/Crystal. Gave you all of Kanto. Certainly had its flaws with the level curve. Was still nice to revisit the "several years later" version with new sprites, a new battle theme, and a remixed gym order. Kind of offered new Pokemon too. (Literally never sees Slugma or Magcargo in Johto, even on trainers, minus maybe the Battle Tower.)

Worst: Red/Blue/Yellow. Almost named Scarlet/Violet here (not counting DLC). Viewed Cerulean Cave and Mewtwo as less interesting than getting some character dialogue post-game.

Edit: Forgot about Scarlet/Violet's 7-star Tera Raids. Enjoyed those. Ranks it quite a bit higher than second-to-last.
