I had a very similar experience as the author: I used and adored Arch, but the rolling updates got to be over whelming. Fedora (not Silverblue in my case, I still need to try that out) was the perfect solution. Very similar in philosophy to Arch, enough so that the Arch wiki is still 95% applicable, but very stable within major releases. It also was a bonus that learning Fedora also taught me CentOS/RHEL at the same time, which started coming in super handy when I needed super-stable and/or server-side OS. Nearly all of the skills (and even scripts) are fully compatible with both, with only the occasional minor difference. I still have a huge warm spot in my heart for Arch, but I rarely use it anymore (mainly on my pinebook pro for building ARM packages of my software).

It's definitely time for me to try Silverblue
