Lufthansa had a neat system at JFK where you would taxi the plane right up to a hangar, the nose would actually be inside (or we'd get towed in, can't recall), door would open and they'd shoot all the pallets out the front and right onto big shelves for sorting, or something to that effect...much faster than K-loaders out the side door. I am sure this was pretty expensive to have a building set up this way, though, so likely not often duplicated. And the tall pallets, if aboard, would still need to go out the side door.
Having both doors is the way to go IMHO, though we did well with our -100/-200/-300SFs too. There were a few planes (World Airways was the customer I believe) that ONLY had the nose door...though this would limit you on pallet height for sure...not real popular I imagine. There is a slight weight penalty of course but I am sure this is offset by the increased utility...

I disagree with your first sentence. At SQ, for the most part, the nose and side door are used at the same time. Not only is the nose door useful in outsized cargo, but it also expedites loading/unloading normal sized cargo. Most of our stations have the ground handling equipment to utilize both nose and side door.
60 minutes is a pretty average time to unload/load using both doors, while 90 minutes is pretty accurate for using the side door only.
