Ask HN: How Do I Stick with GNU/Linux If Important Apps Crash Frequently?

I've never owned a Mac. I haven't used Windows except transiently for about 4 years.

I'm currently on a Dell XPS 13 9360 (Late 2016) Developer Edition with the stock Ubuntu 16.04--in other words, about as orthodox a GNU/Linux setup as one can have.

For work and studying, I use some non-free apps like Slack, TeamViewer, and Zoom. All of them have crashed or behaved weirdly at critical times when I needed smooth, stable operation.

So I've been thinking about getting a Mac. I would rather stick with a (mostly) free OS, even if I have to use some non-free programs at the application layer.

The problems I experience do not tend to surface with software like Chromium, VSCode, etc. so maybe I shouldn't be blaming GNU/Linux. But I also have things to do and a family to feed, and don't want to dig in my heels and waste time and energy diagnosing problems--I'm a developer, not a sysadmin!

Is my experience with proprietary apps on Ubuntu typical? Is the situation on Macs truly better? What can I do to improve my GNU/Linux experience (again, without becoming a full-time sysadmin)?
