- Adobe Creative Suite. They will probably never release a Linux version
- Industry standard music production s/w

- Office Suite which is compatible with MS Office shenanigans
This is not me. But the kinds of people I’m encountered in my social circle. I’m in the CS/Research industry, so all my tools are linux compatible and have been a Linux user for the past decade.
I think it’s better to have a realistic expectation of Linux rather than consider it a 1:1 Windows alternative. I agree with your last para fully.
