FWIW, hex-shafted screwdriver bits, whether PZ or PH, fit comfortable
into an old-fashioned brace. With that arrangement you can apply
considerable um...axial force to keep the bit in the screw head and
stop it caming out and ruining the screw head and/or the bit, and you
can exert a lot of torque at the same time, probably more than with a
hand-held electric screwdriver.

For "out", yes.

For "in"? Torx! Using Torx screwdrivers on wood screws is fun: just enough axial
pressure to keep the head in place --hardly any-- and the rest is torque.
