Coilovers are more stiffer. meaning better cornering but sacrifice ride quality. U can also adjust the ride height to what u want.

Drop springs are more softer than coilovers. Depending on how far u wanna drop, they usually give a comfortable ride quality. Since it is softer... not as good for cornering unlike coilovers but better than stock. They are not adjustable so once they are on then u are at that heighter forever untill u get another set of springs with different ride height.
