My $.02 from lots of heavy use of impact drivers, even within brands you can run into a dud bit. 99% of what we drive are torx (not counting drywall). You will need a new T25 for every 750-1000 screws. Phillips are way worse, probably half that life. I buy the lumber yard bulk bits, usually Sabre. Honestly, they usually get lost before they wear completely out.
