Generally the only reason I can think of to use rockets for landing is when using a chute isn't practical. That is, under vacuum or low pressure environments, or when you need a landing speed of essentially zero and don't mind going to the expense of achieving it with rockets.
If you have spin on landing and you apply a pitch or yaw action, you'll get gyroscopic precession as the response. Depending on your control software, it may or may not be able to determine the correct application of thrust vectors to achieve the desired attitude and trajectory while rotating.
Control vector time lag also gets more interesting with rotating objects.
And landing while spinning is likely to be a drag - all over the ground.
