I have used Snap-on digital (with turn angle option), Snap-on standard break away, Craps man, Harbor Freight/flee market, Precision instruments slide bar and beam type, and lastly break away Matco. I have yet to use a "Mac" torque wrench, of any kind...
That said, I have 4 (1/4", 2x 38" [flex and straight], 1/2") Matco torque wrenchs and one 1/2" PI slide bar (set it and forget it, as we nickname them) in my tool box at work. I dropped my flex head Matco 3/8 drive right on the head, even gave the head a little dent. Sent it to be re-certified, it was only out 2% from specification.
