Horizontal hinging produces the purest of impacts. The ball does not “leak” off the clubface because the ball compresses on the clubface longer. Angled hinging produces a fade because the ball slides up and off the clubface.
But neither hinging is longer or shorter since Hitters mash the ball harder, use more right arm muscle driving into the ball with extreme prejudice to overcome any lose of distance the hinge produces. Swingers with pure impact, the spin of a draw on the ball wouldn’t use a hard driving right arm and jeopardize the CF nature of the hinge motion.
So without factoring in other skills and equipment- both should drive the ball as far as you can.

Top five driving distance in PGA (7 May 05):
1 Scott Hend 315.2
2 Brett Wetterich 307.1
3 Hank Kuehne 301.3
4 Tiger Woods 301.1
5 John Elliott 299.9

hmm.....who hits with the driver? On the other hand, who swings? There is a reason why 95% of pros swing with their drivers (with horizontal hinge).
