Command line: Linux wins by a mile. GNU gettext has better tab completion (i.e. it will complete parameters and paths). If you work with Linux servers, it's nice to have the same directory structure... and while brew is nothing short of amazing, package management on Linux (deb, rpm, pacman, etc...) is still the best.
Design: A lot of tools have moved to the cloud (i.e. Figma and Canva are getting better) but pro grade design software like Affinity Designer (or Adobe stuff) is still the best, especially if print shops are involved. If Serif ports Affinity to Linux, I will buy it for every machine at my company just to say thanks.
Video: Davinci and OSB run extremely well on Linux so life is good :-)
Development: Honestly everything is better on Linux... but no Xcode, which is required to distribute to the App Store. Xcode is a nice IDE, but most of the work I do is in JetBrains IDE (GoLand, PyCharm, WebStorm... and occasionally C Lion).
On the hardware front, Apple still makes great hardware, but some of the PC manufacturers are making great machines, too (LG, Lenovo, Dell). I'm particularly happy with LG's Gram 17" which has a giant screen and is an ounce or so heavier than a 13" MacBook Air. The M1 and M2 are fast, but a modern i7 or better is plenty fast and you can get one with 32GB for cheap.
You will probably never find a replacement for everything, but eventually you get to a threshold where the "Apple Hates Me" vibes > "Not quite everything I want", then you have somewhere to go when you flip the table... You will probably still hate it initially, but the nice thing is that you can work on it, making it into what you want, and unlike with Apple or MS you can make progress... it will stay how you put it, because the authors of the software are not working against you. i.e it gets more comfortable over time, and less of a battle over time.
Admittedly how easy this is, is highly subjective, e.g if you are a media person then it's going to be painful whatever platform you head to (although I hear audio and video editing alternatives are getting better).
