Help: I ??just got offers for Qingdao Hisense Kelon air conditioners and Foshan Midea air conditioners. Which one is better?

I really don’t know which one is better between Hisense Kelon air conditioner and Midea air conditioner. The personnel changes in Kelon are not big, but the changes in Midea are faster. If they are promoted, Midea may be faster. The two companies are very close. In terms of the company's main business, Kelon is a professional air-conditioning manufacturer. In the past two years, Acquired by Hisense, Midea is a group company and air conditioning is just a business unit. Both are big companies, the decision is yours!
