Best Option for 2D Platformer Controls

I've just begun working on making the basic controls and movement for a 2d Platformer. The game will mostly (if not entirely) be in 2d. I'm using Sprite Manager 2 to handle the sprites. My question is what is the best base for handling character movement. I've started using the built in charactercontroller, but I'm having my doubts about how effective and accurate it will be. Should I just make movement (and collision detection) from scratch? If so any tips on how to go about this? Should I use rigidbodies? Should I apply physic forces? I want something simple and effective.

I think I would prefer to not use the charactercontrol if only because it uses sphere based collision detection and I would much rather have a cube/square.
