Some of the internal parts such as CPU and GPU are made by either Intel or AMD so it doesn’t really matter which brand you buy, it will have either of them. But, some of the parts like battery, design, display, fans, etc will vary as different brands have different priorities: some of the laptops have a featherweight, some have aesthetic looks, etc. It doesn’t matter unless you buy a laptop from a reputable and well-recognized brand as they will not give a single reason for a bad experience.
