2D Sonic games or 3D Sonic games? Why?

[TomaTito]

Oldskool 2D Sonic.

Tried to like Colours, but I sold it since I had to go through the 3D sections just to get to the 2D stuff, and 2D was gimped needing double jumps/homing attacks/etc to pass through block platforms with a small Sonic due to the stretched out view.

I played the Sonic Lost Worlds demo but it only had the 3D level, and the 2D levels look to have the same faulty design.
