I tried this experiment last year. Bought a DELL XPS 13 at Costco, put Ubuntu 18.04 on it and dove in. I've been a Mac guy for ~10y just like the author. Worked at MS prior to that, so lots of Windows.
My experience is that it's one of those things that seems great on day 1, OK on day 1, and so on.
Spoiler, after about 6 months I gave up and went back to Win10, which is really improving rapidly with WSL, etc. I run an Ubuntu VM in Hyper-V if I need "real" Linux for something.
It's death of a thousand cuts. Beyond random Linux config issues, the UI can be laggy, the power management is terrible, etc.
I enjoyed the fiddling but just don't have time for it.
