As someone who has moved back and forth between Mac and Linux around 3 or 4 times since 1992, Linux is actually surprisingly reasonable. For laptops, I just buy from Dell, with Ubuntu preloaded, and everything works. (Dell's build quality isn't as good as Apple's, so I usually spend extra for Dell's next-day on-site service.) For workstations, it's usually pretty straightforward to get something that Just Works.

After that, I've got Chrome, Visual Studio Code, Steam and a full suite of command-line tools, which covers my personal essentials. But if you rely heavily on something like Photoshop or the MacOS X Omnifocus application, then you might find much larger holes on the Linux side.

As a matter of principal, I consider myself too old to troubleshoot Linux without getting paid for it. It turns out that I virtually never do that, so I'm pretty happy. Really, buying pre-loaded and fully supported Linux laptops eliminates 80% of the pain, and nearly all of the remaining 20% can be avoided by refusing to get clever.
