What is the Most Irrelevant Smash Bros. Game?

[umegames]

Funny this thread asks this question, as i have been thinking about this in recent days. for me, ultimate took my vote. I've loved smash to death since n64, but even though ultimate gives me every character, tons of stages and an amazing soundtrack, i feel the game is taking it's self to seriously with trying to be a competitive fighter with all the attention to frame data, techs and combo ability, and lesser on the ridiculous fun factor that we fell in love with during the n64 through brawl era.
There's nothing wrong with it going this direction, but as a fighting game fan, I want my streetfighter, tekken, dbz to feel different from smash. I also really miss things like break the targets, board the platforms, home run contest, smash run etc. even all-star mode got gimped.
