This is what many a pro has told me. However I too can feel the difference; for my timing belt and especially my cam seals, where the cam sprockets needed a 10 mm hex bit, we were fortunate to have Snap-On. Likewise for my spark plugs, where a bendy ratchet was handy. The $10 item would have worked OK too, but the good stuff has more clicks per turn, is thinner and more flexible yet stronger and more precise, it's different. Everyday stuff though and even axles it's Craftsman or lower over here.
Have a good night T0rque!
