"Wolf Design watch winders have a sleep mode to avoid overwinding, but with the Orbita winders, mainspring tension is held constant to assure no overwinding. Which is better?"
The Privee winder and other winders like it have a rest period in between winding cycles, so there is no risk of over-winding. The advantage of keeping the mainspring fully wound is that it will always be fully wound when you take the watch off the winder.
The advantage of the Wolf Designs method is that, since Wolf Designs winders are a little louder than Orbita winders, it makes sure there is no chance of the winder keeping you up at night.
One method is not better than another, but each has some advantages.
