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?

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.

I lean towards Platinum, by virtue of its Battle Frontier and where the Physical/Special split made a lot more Pokémon more viable in battle regardless of how their base stats line up with their type, which was my main gripe in Emerald's Battle Frontier.

I want to say HeartGold and SoulSilver since it took the base of Kanto from gen 2 but heavily expanded upon it. But there's also Black and White 1 and 2 with exploring the second half of the map and providing a decent challenge. Both are genuinely great and fun to explore.
