With a Rolleicord, I will advance the film but won't cock the shutter, unless I know I want to take another shot immediately, because it does not have a shutter lock. Leaving the shutter uncocked prevents accidental release.
With the 2.8C, I will not wind on either, because you cannot set the speed to or from 1/500 once the shutter is cocked (yes, I'm familiar with firing the shutter with the lens covered and then using the multiple exposure facility to set 1/500, if you need to, and I have done this, but it's just easier to advance the film, after I've set the shutter speed).
With a TL Electro X I usually won't advance the film because it can drain the battery. It's not such an easy battery to find in Tasmania, so I don't want to do that.
With the 500C/M I always advance the camera because this is the simplest way to prevent well-documented problems from occurring.
With a Contaflex or a Bessamatic I will nearly always advance the film, because otherwise you can't compose a shot, as they do not have instant return mirrors.
So it all depends on the camera. I suspect a lot of other people who use older cameras regularly, might give the same response for various reasons.
