It's always fun to see these kinds of threads.
First, I don't judge airports nearly as much on traffic or distance from city center etc. as I do on the interior of the airport itself. As in "which airport would you rather have a 4 hour layover in".
OK, that said, Some of my favorites in no particular order.
Domestic:
ATL
DEN
LAX
MIA
EWR
SAN
International:
AMS
ICN
NRT
SIN
GRU
Most all airports in Brazil except GIG
Most disliked Airports.
Domestic:
ORD
JFK
DFW
DTW
MDT
International:
MNL
MUC
GIG
And probably a lot more that I haven't seen yet
