Lol I was more talking like it looks like one of the coolest. But like, if you wanted to rate Final Smashes, Id say the best are like, in no order, Bowser, Diddy, Yoshi, Wario, Ike (cuz Jab > Great Aether is a thing), Pikachu, GW, and Sonic, cant really think of any better than those couple. Like, maybe Samus', maybe also ROBs, and maybe the Landmasters, but Im not sure on those really. But I cant see a competent player ever not getting something out of those characters I mentioned's final smashes. Obviously there may be better final smashes in the terms of actually what they do when successful, but when it comes to being able to reliably connect with your opponent or get something out of them consistently, I think those are the best ones.
I think the worst are probably, in no order, Mario, Peach, Link, Zelda, Sheik, Tink, ZSS, Pit, ICies, Kirby, King Dedede, Olimar, Falcon, Marth, Ness, Lucas, and Snake, whether it be from being easy to avoid (Peach's, Ness', or Pit's for example), hard to connect with reliably (Link's, Falcon's, or Marth's for example), just straight up being bad (Mario's or Kirby's for example), or something else maybe.
Anyone who's FS I didnt mention I either think is decent or forgot lol.
