Brawl easily imo. I love the controls and movement the most of the series. The "story" is really good and the roster is amazing also.

All of them would be the easiest answer, but I gotta go with Brawl & Sm4sh. Mods-wise, it's gotta be Project M EX Remix/REX for Brawl, & HewDraw Remix for Ultimate.

I try ultimate but is weird in the gameplay i think smash 4 has the best gameplay

the one you enjoy the most :-)

i played ultimate at a convention one time and i thought that it felt slightly better than smash 4
