the most significant practical change is when driving screws into vertical surfaces. Supadriv has better Chunk, producing screwdriving simpler with a lot less came out when driving screws into approximately vertical surfaces.

in actual fact, it is part of the look that slotted screw heads will strip relatively quickly when a lot of drive is applied. This helps prevent overtightening.
