Incentive of using _integrate_forces on RigidBody2D?

Zing

I am aware that one can control the RigidBody directly using the state argument in the _integrate_forces method. However, how does this help over using the _physics_process method and controlling the RigidBody indirectly? With the _physics_process method one can also control for time with the delta argument. For example:

# Using _integrate_forces, moves the player left when pressing the move_left button.
func _integrate_forces(state):
	if Input.is_action_pressed("move_left"):
		state.linear_velocity.x += -movement_speed

# Using _physics_process, moves the player left when pressing the move_left button.
func _physics_process(delta):
	if Input.is_action_pressed("move_left"):
		apply_central_impulse(Vector2(-movement_speed, 0))

These have the same result, except theoretically, one could control for time in the _physics_process method. Why shouldn't I always use the _physics_process method instead?

Use whatever works for your project - they are both useful for different things. On my current project, I do almost all rigidbody movement by applying forces in physics_process. I also use integrate_forces when required : player standing on a moving object (keep player on object), limit how fast player can rotate an object after picking it up.
