When you say "best" you need to define what "best" means. Does best mean computing value for the money? Reliability? If you are talking about being an simple user of laptops or desktops that can run sophisticated programs and are not simply glorified tablets with keyboards in closed computing environments, and your not a business, your world is basically broken up into two options: Mac and everything else (meaning Windows / open source Windows alternative operating systems). Macs give you a bonus of generally being very well built, and much more secure than Windows devices since only around 5% of the world's installed base are Mac devices. Mac tends to be a bit pricey, but looks sleek, is easier to maintain than Windows 10 computers (as many people will attest to due to constant upgrades) and is preferred by many artists, multimedia developers, and higher end users. Windows tends to be more interoperoperable with businesses and organizations, and is available at a lower price point. Some of the highest rated Windows computers according to consumer satisfaction right now are the LG desktops. I have had great luck with HP's, but they tend to be loaded with bloatware (programs) that you do not need and will slow your machine down. Most laptops and desktops use interchangeable parts made in China and newly emerging manufacturing areas. It all depends on what you want to do, what operating system you want, what you can afford, and what your local market can best service after the fact.
