Yoshi for me, I guess they sell really well that we get so many :p
Star Fox, more indifferent than anything, I greatly enjoyed Pilotwings Resorts and the SNES one, and if they are at least something like those, then it's more of not having tried enough SF. I do like the characters, but I think they take themselves too seriously. Multiplayer is fun in what I've tried. Guard was really fun; I think they needed a new IP for it though, a little more significant lore to be like FNaF or something.
I like the rest of major franchises, from Mario & Sonic to Wii Fit to Bayonetta to the fun toy that Wii Music was.
Yoshi however, no matter the rationale, simply no.
