Of course, those are all in Asia. In Europe, MUC and ZRH seem to be pretty popular (kind of funny... FRA does great in the "official" rankings, but the customer reviews are largely dismal).
For hubs in the Americas, I think DEN is good, and IAD is getting there with its new tram, terminal improvements, and forthcoming Metro connection. PIT *was* a great, easy, super nice hub, and still could be if anyone wanted to make it one! SFO is 2/3 of a great airport -- the International terminal and the new VX terminal 2 are outstanding... but due to weather, no one is EVER going to call SFO "efficient" .
Now, to pick apart and gainsay some of the other suggestions...

Isn't ATL overly crowded and gets a lot of delays? What about IAH? Barley any delays, lots of destinations, comfortable facilities, decent amount of schedules.
IAH is pretty "efficient" from a flight standpoint, but from a pax standpoint, it kind of sucks. The dining options are limited, and it's a pretty huge spread from the A-B terminals to the C-E terminals. Plus, I have kind of a grudge against an airport that has screwed up every time my parents have gone through needing a wheelchair, or the one time they lost my luggage.

CLT in the US is actually very nice.
Only been through once, but friends have all said good things about it, and customer reviews are good.

from my perspective, nothing beats....
The Hartsfield-Jackson Atlanta International Airport
It is pretty amazingly huge and efficient as a connecting hub, but as a place to ARRIVE -- or just connect through customs -- it still has some significant problems to overcome. Definitely up there though, for the US.
