A torque wrench, used in a less than perfect manner! beats the ass off
a screwdriver twisted untill your teeth grit. Twice.
(The old fashioned "Farmer Tight" method most traditionally use.)
I know using a torque wrench usually results in a big surprise in how
little effort it takes to properly tighten most fasteners.
Often am uncomfortable with how tight I haven't made lug nuts.
100ft/lbs sure is a long way from pulling on the bar till I grunt.
