I also dislike changing terminals anywhere - but even more so airports. For example, transfers between Tokyo's Narita airport (international) and Haneda airport (domestic) is particularly annoying, given the $40 charge and 1.5 hour inconvenience.
I don't transit in Asia much preferring to spend a night instead. For example, when arriving in NRT, I usually stay in Tokyo or Yokohama overnight for the easy morning connection to HND. Similarly in HKG, MNL, SIN, TPE, BKK, SHA and elsewhere, I prefer to stay overnight. KUL is a bit far from the city so when possible I like to skip over to LGK or PEN for the night. Even in SYD, I always try to stop at the Novotel Brighton Beach so I can watch the local TV, get sand in my feet and devour a kebab from the snack bar on the corner opposite the hotel (although the SYD taxi drivers are never happy taking me such a short distance from the airport).
So given my overnight preference, transit factors are not so important (for me) when considering my favorite/ worst airports. My priorities lean more towards clear signage, a light and airy feeling, decent lounges, polite staff, reasonable security precautions/ lines, good duty free selection and prices and efficient access to/from the airport.
