I haven't really had a problem getting anything done in Big Sur on my 2017 Macbook. Before my Macbook I had a Lenovo X1 Carbon with Arch and KDE; I really loved that setup but there are several conveniences with Macs. I prefer Excel to LibreOffice for example, and I like messaging integration with iPhone and all of the applications I use are really nice; I always felt like there were a few apps on Linux that were not well designed and I had to use them anyway. But, Arch has such a great package management system. You can easiy revert to any previous version of a package, you can quickly do a binary search to find which package broke you after an update etc. Homebrew is a total garbage fire. A couple weeks ago I typed "brew upgrade git" and it upgraded the version of every homebrew package on my system. My Postgres database wouldn't start because my databases had to be upgraded. I had a deadline... Also for some reason I'm more likely to run into build problems with certain native packages. I'm really on the fence about what my next computer will be.
