This is crazy. Yoshi's Island was - and remains - a near perfect game. It's a game that I will sometimes start up just for a couple of minute's nostalgia and find I've lost hours to it. Every part of the design works in harmony, imo, and the gamefeel is just immaculate. It plays like a dream.
Absolutely flabbergasted by this take, but I love a good controversial opinion so carry on...!
And just to clarify my problems with DKC, they are:
-Loose gamefeel
-Inconsistent / unclear collision spaces (especially background platform edges)
-Poor camera positioning of your character (it needed to be zoomed out a bit, with your character closer to the edge of the screen, it feels too tight)
-Ugly art design of enemies (subjective, yes)
-Inconsistent difficulty
-Over-reliance on bonus areas and animal buddies
But I will admit that there's a lot of great level design in DKC, incredible music, and it IS a good game. It was just overrated at the time. DKC2 is far, far superior, and I still have many of the same issues with it. One of the most mind-melting modern takes for me is that Rare's DKC games are better than Retro's. I don't think the games are even in the same galaxy, quality-wise. Retro's games are two of the best platformers of all time.
