Used the new T3 international terminal during a recent trip. You no longer have to deal with the masses outside the entrance doors much more space to move around the check-in area and the security check has been moved to immediately after immigration meaning you no longer have to worry about missing your flight due to security if you go to the lounge. The main terminal area is much nicer than the old one though as another poster has noted the shops are overpriced lounges are nicer as are gate waiting areas. Queue control also seems to be better though I was leaving on a Saturday night when traffic seemed pretty light. Alas there are still some teething problems. My main complaint was the shuttle service from the domestic terminal (1D) to the international terminal. The bus itself is fine but you're dropped off at the very bottom level where there are no luggage carts to be found. This forces you to lug your heavy bags up a seemingly endless series of travelators to the 3rd level - no easy feat when you're tired. There is still insufficient place to sit if you arrive too early to check in for your flight. And although Wi-Fi is free you must have a working mobile phone to obtain a password by SMS - a big problem if you're a visitor without an international-enabled phone. They don't even offer a pay option anymore. And finally I don't care for the gate setup - similar to Bangkok or Singapore where you have a second (useless) security check then a waiting area to sit until your flight is ready to board but the waiting area itself doesn't open until about an hour before boarding. If you're too early there's really no place to sit in the main terminal unless you have lounge access or patronize one of the overpriced restaurants.
