I love 2D platformers, especially metroidvanias. Some of my favorite ones (not just metroidvanias) are Battleblock Theater, Dead Cells, Hollow Knight and the Ori games.

I also think 3D Platforming sucks, so I try to avoid games, where this is the main gameplay. I’ve played some, like Portal or Grow Home, which I thought were good, but you probably won’t ever catch me playing some 3D collectathons or something.
