Which is better, Mitsubishi Heavy Industries Haier Central Air Conditioning or Gree?

Generally speaking, a good central air conditioner is a lot of money, and Gree is affordable. My home is Gree central air-conditioning, which is not as unbearable as what is said upstairs. In particular, heating, because of domestic research and development, is relatively grounded, plus heating wires, so the heating effect is fast. The house next door is Daikin, and the cooling effect can be said to be very amazing, but the heating is very bad. None of friends or relatives of Mitsubishi Heavy Industries Haier have used it and do not comment. However, pure Mitsubishi Heavy Industries is not as good as its own mitsubishi electric, and it is better to import Hitachi.
