There is no actually good alternative to Photoshop. gIMP is not remotely in the same league. Pixelmator and Affinity Photo are brought up but they're also like nano vs emacs. Photoshop doesn't run on Linux AFAIK. I'm sure for a graphic designer the same is true for Illustrator. The cheaper alternative exist and you can maybe get by but there's missing so many features.
If you're into games there is really only Windows. Same for VR.
I'm sure there are other categories.
I did serious dev on Linux and that dev didn't require any games or apps so it was great and I loved it. It ran my editor of choice and otherwise I only needed a browser and a terminal. But as soon as I step out of that small subset it's pretty much MacOS or Windows only, at least for the things I want to do with my computer.
VirtualBox has a 'seamless mode' as well, I wonder how well it works on a Linux host and a macOS/Windows guest.
