I’ve definitely worn out some torx bits, but you’re very right. I think flat blades should only be for ornamental/aesthetic reasons and Phillips need to be done away with.The world needs to obsolete flat blade and Phillips screwdrivers.
Torx is the only way to go.
I helped put up 500' of privacy fence for a friend awhile back. Never had to change out the Torx bit.
Had it been a Phillips, it would have taken dozens of bits resulting in multiple stripped head in the screws.
