Yeah, the positive aspect of over/under is less about cable stress and more about not twisting the cable into a spiral so it spools-off cleanly and lays flat when unwound instead of wanting to curl up. The negative aspect of over/under, and it is a big one unless you figure a way to manage it, is that you have to keep the ends from accidentally passing through the main cable loops or else you get a huge mess of knots next time you play out the cable.
I use both. I typically overhand coil short cables that can be untwisted easily, and over/under long ones that would be hard to manage. On the over/unders I make sure to connect the ends or tie them off in such a way that the'll be no chance of a resulting macrame/fishline type mess.
