I guess my point is I don’t agree with the generalization of “the Germans were more advanced, they were just outproduced/fumbled too much with too advanced stuff”.

I agree as well. There were a couple areas where the Germans were undeniably ahead, the Me-262 and V-1/2 in particular, but that didn’t correspond to any general technological superiority.

The US/UK were well ahead of Germany in things like strategic bombers, radar, proximity fuses, and of course the atomic bomb.
