My favorite would be Beijing as I spent quite some time there and have fallen in love with the city. My second favorite would be Shanghai as I also have spent quite some time there but not as long as Beijing.
Hongkong is neat and well-organized, but because it is too small, I am not accustomed to narrow roads and high-rises compared with Beijing. Either business and living environment or public service of Hongkong is superior
