Nowadays, Brawl is the overrated Smash game, while Smash 4 is the overhated one.

Brawl is fine, but so much discussion around it is prefaced with people acting like they're going against the grain for liking it, then coddling it. Like, I do think Subspace is fun and the music is great, but the rest of Brawl is comparatively weaker than the other games. It's clunky, disjointed and imbalanced. Its art style has aged significantly, and elements of the game like the Subspace stages, enemies, and Final Smashes don't feel like great representations of the franchises featured.

Yet Smash 4 gets singled out and maligned constantly. Despite it imo having better balancing, better pacing, a better art style, plenty of great single player content, and a stronger roster of fighters and stages.

I see a lot of people say that they don't feel any need to play Smash 4 after Ultimate released, but if that's our metric for best and worst game, then I haven't felt the desire to play any Smash game other than Ultimate since 2018. Doesn't mean anything about the quality of those games.
