Box vs Capsule collider for player

Hi everyone,

What are the advantages and disadvantages of using a box collider for a character? I have a 2.5D platformer where the player has a box collider + rigidbody attached to it and everything works like a charm. But, many tutorials online use a capsule collider. Why? Is there any specific reason for it?

If the platforms also have box colliders the jump can be rather unforgiving, if the jump is just short of landing it will slide down the side of the platform.

Also you can stand right on the edge of a platform with a box collider, with a capsule you would slide off.
