My doubts were always whether the same or almost the same couldn’t be said about “inbus” (I don’t know the proper English name for that but it’s like inverted hexagon head - a hexagonal socket), which was already well established but I tend to believe that Torx allows even more torque than “inbus”. Definitely beyond the range of PH or PZ.

Inbus (in USA 'allen key' or 'hex key') doesn't allow as much torque. I 
have ruined more than one of them when applying too much torque. Never 
happened with a Torx so far. It's much more likely that you'll twist off 
the whole head of the screw.

I have not stripped a single Torx yet. But more than enough PH / PZ or
