There’s no such ‘best’ and ‘worst’ in the motherboard manufacturing industry, all companies make good boards as well as bad boards. There’s no way to objectively determine which company is the best, some prefer one company while others prefer another company. I know it can get confusing on which motherboard to buy since all of them have a wide variety of choices. The best way to choose is to search on Google based on your requirements, and read/watch reviews of whatever options you shortlist. Some factors you can include in trying to decide on a motherboard/manufacturer are cost, ease of claiming warranty based on your location, looks of the motherboard, previous experience with the brand, etc.
