Call of Duty better Aimen?

So I have a question. Do you have a better aim if you switch off the controller vibration on the Ps4 or is it better to play with vibration?

Go to War Zone and there's training for Aim

Better without, why should it be better with? Then everything wobbles and you can't hold it against it anymore

So I always turn off the vibration. I find it disturbing and can definitely influence the aim
