Cogged belts generate less internal friction especially when turning around tight radii and less heat generated within the belt equates to longer belt life. In a cogged belt all the strength cord is in the upper/non cogged section so they are more flexible than the old style.

Yes, I've seen a couple of broken 356 belts but they were VERY old and not much elasticity left in them I guess. Back in the 60s a common replacement for the 356 belt was Gates 85T or 86T and later an 880T which were truck & bus belts also used on GMC, White, and others.
