What is your favorite 2d and 3d mario level of all time

3-D game: Super Mario Odyssey's final boss + ending
2-D game: If New Super Mario Bros. Wii counts as a 2-D since there's no z-axis movement then the final boss in that game. If not, then I guess World 1-1 from the original game since I don't know any other ones lol.

2D: Probably 8-7 from NSMBWii because it's such a cool idea to have Mario riding on a rollercoaster for the whole level and have to jump around everywhere, even moving to different coasters, while everything around him burns and sets on lava.

3D: Tick Tock Clock from SM64 is such a cool idea. It is conventional for a Mario level theme, it is very spacious with lots of obstacles to traverse over, and I love the idea of being able to make everything move quickly, slowly, not at all, and even randomly. I could probably come up with one I like more if I tried hard enough, but meh.
