Which is better, Sheraton or Hyatt?

In China Hyatt Group, hotels in Beijing, Shanghai and Dongguan are the best in Hyatt Group, but Hyatt Hotel is the lowest in Hyatt Group, 1 brand. The highest in Hyatt Group is Park Hyatt, and then Hyatt is the last, so many people know Hyatt, but they don't know that Sheraton is also the world's top hotel management group, and its hotels are quite good. However, the main markets are still in America and Europe. If I am in Asia, I feel bad 1 minute. Hyatt Group, I know so much about these two groups, and I hope I can help you.
