Off for the PS3.. Always on for Xbox one because mainly you can't turn it off... but also because of the special bumpers in the XB1 controller and in racing games its perfection
I like using it since it makes things a bit more immersive in racing games. Well I know that the best experience for racing games is to have a racing controller but you know, vibration is still a good way to have some kind of feedback while playing ahahah
