No, I don't think this is the best roster.
I don't find this roster very appealing overall.
I mean, I'm going to main Villager and probably DHD since I think they're clever, but...
The cuts from the roster for this game were appalling. Lucas? Wolf? ICE CLIMBERS? Seriously, Ice Climbers? Talk about awful-- Smash was honestly the only thing that the Ice Climbers had to keep them alive in gaming, and now they've been cut. Even though I never used them, I honestly really liked Nana and Popo, and it's sad to see them gone (at least for now).
If a franchise has a certain amount of reps in one iteration of Smash, that franchise should keep that number of reps or raise the number of reps, since it clearly deserves that amount of representation.
Like StarFox-- if it was worthy enough to have three roster slots in Brawl, there's no reason it should have only two in Sm4sh, ESPECIALLY when a new StarFox game is coming out next year.
The Nintendo newcomers that we got don't really justify the cuts for me. Some of them were great/popular (Robin, Palutena, Shulk), some of them were out of left field (DHD, Villager), and some of them were just downright stupid (Dark Pit. Just. Dark Pit).
But even though some of the newcomers were popular, there are plenty of other popular characters that I believe deserve a spot more than them (even though I have no personal feelings towards most of them), such as Ridley, K. Rool, Dixie, Isaac(the only one I seriously care about in this list), or Mewtwo (though I do think Pokemon would've become oversaturated like the Mario franchise if Mewtwo was included with all the other Pokemon we got).
Even though I'm personally not a big fan of Donkey Kong (I never have been, sorry ;; ), I do think it needed another representative in this game. Mario got three more reps (Rosalina, Dr Mario, and Bowser Jr), Kid Icarus got two, and DK got...none? Nothing? At all? Really?
But thank goodness for having an edgier Pit on the roster in his own slot, because that was incredibly necessary. [/s]
And that Falcondorf-- it's not like Ganondorf deserves his own unique moveset, or anything. [/s]
I think Nintendo needed to add more new franchises to the list. The first one that comes to my mind is (obviously) Golden Sun, but Rhythm Heaven or something else too that is currently escaping my mind. I don't know. It just seems to really be lacking in that area.
The 3rd party additions were great, though, if not a little predictable. I'm not surprised Snake was cut, though I feel bad for the Snake fans.
I'm happy Megaman and Pacman made it in and I'm glad that Sonic is back (even though I don't really care for Sonic, either). So, the third-party side of Sm4sh seems pretty good.
Anyway, whatevevr saltiness I had aside, I don't think this roster was nearly as good as it could've been. I don't think it represents Nintendo as a whole as well as it could have. However, Sm4sh's gameplay seems much better than Brawl's, and for that, I am grateful.
Maybe I'll warm up to it in time, but right now, I have a bit of a bitter taste in my mouth.
