The GH is one of the best Hyatts in the world, but it does not make the "10 best hotels in Hong Kong" list, while both MO and LMO do. Better still are the Peninsula, IC (ex-Regent), FS and W, while the "great value" option is the Langham in Mong Kok (edgier location but more luxurious hotel). All of these have far nicer suites that the GH, fwiw. Like three times as nice. All depends if you are looking for luxury or just floor space.
