Flying MU is quite ok in my opinion. If the fare is right, it is.. They're not a really good carrier but totally flyable. PVG is rather a disaster - PEK (T3 especially) and CAN are miles ahead. Not that much that MU can do here - maybe they should move more flights to NKG which has a fancy new terminal (and nice lounges, even domestic) - more central in Jiangsu anyway
