1. Brawl
2. Ultimate
3. Wii U
4. Melee
5. SSB 64
Not played: 3DS
Brawl wins due to the Subspace emissary. Ultimate is close second due to the rooster and storymode
Wii U has a great rooster and nice gameplay additions, plus the editor
Melee just has tons of awards at the end of each match that I'm missing, but the rest hasn't aged well.
The N64 game is too small and N64 graphics in general to ugly to get any higher in the list
