Favorite
Super Mario 64 - It's one of my favorite Mario games just in general, even over 2D ones, and until Odyssey, I was bummed they mostly dropped this style of Mario game after Sunshine as Galaxy started to shift the series away from that style and then they were just gone till Odyssey.
Super Mario Odyssey - It's what I wanted for so long from the Mario series, since Super Mario 64 and it's a wonderful game.
Banjo-Kazooie/Tooie - These might be my favorite platformers of all time as they took what Mario 64 was doing and just made a deeper game I think and they are so fun. I'm still hoping for a proper revival of the series someday.
Jak & Daxter - I didn't like where the series went after the first game, they dropped a lot of the platforming for guns and cars and were more like the Ratchet & Clank games and other games at the time, but the first one I remember really loving. I need to go back and see if this one holds up at all someday.
Crash Bandicoot - It's a quirky 3D platformer series, but I dig it as it stands out from all the others.
Least
Mostly Anything Sonic - I think the majority of 3D Sonic games are pretty ass, even for the time, though the worst would be like Sonic '06.
Super Mario 3D World/Land - I don't think these are bad games at all, but as far as being "3D Platformers", they are barely different than the 2D games and just lost any of the charm the previous 3D Mario games had and just rehash far too much old Mario ideas.
