On a controller, they map the sticks to a curve so that most of the area is used for micro movement and only the very edge is used for large turns.

IMHO that's the only disadvantage a mouse will have over a controller, unless you can adjust the sensitivity through the game.

Yet adjusting it really high, it will skip 3-5 pixels to all directions, hence loss of precision, - which is the very point!
