Torx is the best of both worlds. They just don't slip, in my experience. YMMV
I agree. Since I have a Harley, I have plenty of Torx screwdrivers :-)
The only thing IMO that came close was the Robertson (square) which was invented in Canada and not terribly popular south of thhe border. For hard to reach areas the Roberton screws stay on the end of the screwdriver much better than anything else.
