I thought T2 was perfectly fine. Not the architectural monument that HKG or ICN is, but comfortable, pleasant, and functional. T1, though, was old, dreary, not well-laid-out, and in much need of renovation. Sort of like T1 at Changi, only worse. Changi, though, is getting the facelift it needs. It would be nice for T1 TPE to get the same.
