Were the Germans really that good?

And my own feelings on the North Africa campaign are that it was always a battle of logistics more than tactical prowess. Both sides were able to push the other side back until the supply train couldn't keep up the advance and the other guy's supply line finally got short enough to catch their breath.

I don't think you can blame the lack of supply on the British stopping around Marble Arch in 40 and 41. Both tiimes they stopped because troops (and lots of troops too in terms of percentages) needed to be withdrawn for other commitments around the Empire. The Allies logistical problems were not the same as the Axis Logistical problems.
