From my experience I'd say length is an obvious issue. I've played in rounds where the higher handicapper is taking two shots to get to the lower handicappers drive.
But, the main difference is consistency. The lower handicapper will have a swing that s/he can trust and rely on 99% of the time. Take that to the extreme and you'll hear stories from the tour such as the Seve one where he was hitting iron shots and his caddy was catching the ball with a baseball glove. This is why I always advise newcomers to the game to get hold of a 7 iron and hit it until your hands bleed. Doing that will teach you what YOUR swing is and what ball flight/shape you produce. That way, once out on the course you'll know what shots you can and can't do.
There's also a commitment issue. I see a lot of higher handicappers decelerate as they hit the ball. That leads to all sorts of problems. By and large, you'll see the lower handicapper commit to every shot.
