This is quite likely, yes, given that about a fifth of them–Marth (fucking Marth), Zelda/Sheik (surprisingly), Landmasters!!!, and Glacier–are kind of unavoidable or control a huge amount of space.
But a lot of the hate comes from that fact that pretty much all Final Smashes benefit from being on the most “neutral”, which is fucking bullshit, stage of them all: Final Destination, which a lot of smashboards, even with the meme aside, freaking praise and love (for some reason).
It’s much more difficult to dodge a Landmaster on Final Destination (probably impossible) then somewhere like Pictochat or Battlefield or Bridge of Eldin.
And the general sentiment is that people don’t really want to even try because Final Smashes are automatically broken when it’s only the above seven that are really dangerous.
Hell, the ones you cited, Volt Tackle and Super Sonic, require basically juggling people to death while trying to make sure your FS doesn’t end over a pit or put you in oblivion when you have little control over it.
If it wasn’t for Marth and Zelda (seemingly) being OHKOs, then I would they would be allowed because it’s not like the Space Animals and Marth aren’t going to be whored anyway, so the whole “well only people with the best FSes will be played” argument is rather moot since it’s not like they gave the great Final Smashes characters that people really played anyway. (I.e. Jigglypuff and Captain Falcon.)
But, yeah, fundamental disagreement yadda yadda yadda.
As for the list in front, Ganondorf’s actually survivable. It survived as Snake when I was playing Ezekial45 IIRC. It just hits really hard.
Speaking of Snake’s FS, it’s rather mediocre, especially since the stupid grenade arc downard below where the bulls-eye is.
Speaking of mediocre, I don’t know why people like Metaknight’s FS. It’s such weak garbage. I guess people love the melodramatic pause. Meh.
As for underrated ones, I would say that Wario’s, Ice Climber’s, and Luigi’s are underrated.
Apparently Luigi’s even goes straight through halo-invincibility.
