I see people on another site bashing Donkey Kong Country 3 saying it's their least favorite of the 3 games, but I feel the opposite and like it better than the other two for being smoother. More secrets and cool extras. It was like Sonic 3D Blast and came out when the next gen was becoming popular so that probably has something to do with it not being as succesful as the other two.
It's one of the games I would actually consider the best of Super Nintendo but people say "oh it's not so special compared to 1 & 2"
