If you ever had any trouble with your gear, would you do something about it or might you just return the gear and not bother to mention it?
Yeah there's that as well, if I have any little niggles with rental gear, I'm usually over it by the end of the day, so I just want to return my tub and go and get warm. I might even be left thinking "Gee that oceanic reg breathes a bit hard on the second half of the tank", and unfairly write off a particular brand. For all I know that reg might breathe wet straight out of the box. I like to think I'd mention it and maybe the DM intern who checks my gear in will remember to note it. Maybe the note he taped to the reg will make it through to the service tech before the next day's diving, I don't know. My LDS is pretty sharp though, I think that if something was tagged out, it would make it to the service tech before it went out again. Still a lot of points in the chain for something to get missed.
So as far as fault tracking and reporting there's a definite advantage to having continuity with your gear, as well as the advantage of having the right gear for you, and being familiar with it in the water. Most of us, however, are still having to trust the same person at our local dive store whether we rent gear from them or have them service our own. We're relying on that same link in the chain either way.
