Which brand of gas cooker, range hood, sterilizer, microwave oven is better?

My home hood and gas cooker is Haier, and disinfection cabinet together with set purchase also sent me a V + value-added card, many services are free.

In fact, at first I did not decide to buy what brand, to the mall to compare the appearance of the product, performance, price, or Haier is more affordable, the service is okay, the advertising brand price is too high!
