I always turn mine off. Mainly because, when I first got the car, several times I'd 'nip' out of a junction only to have it cut in and leave me bogged down in front of approaching traffic. I'd much rather have a bit tyre chirp or , if I'm feeling playful, a bit of fish tailing than having it cut in as it is rather sensitive and very abrupt.
But having said all that, you have to judge your own driving skills as to whether you can drive with it off or not.
