Main reason I don't care for torx or hex heads is I had a less than stellar experience with torx grip screws on my Springfield TRP...the grip screws were tightened down so hard on the factory grips that when I went to change grips from G10 to checkered double diamond cocobolo, that one of the bushings came out with the grip screw. When I finally did get the bushing back in the frame without damaging either the bushing or the frame, the screw was stripped out. Necessitated new grip bushings and slotted screws. Since then I've just stuck with slotted grip screws.
