OK. In my impression, your conflict is smooth experience in FW vs learning curve.
The main differences between Fedora and Mint are
Fedora: RPM based, Upstream distro, one the streams is Fedora → CentOS Stream → Red Hat Enterprise Linux → CentOS, Rocky Linux, and etc
Mint: Debian based, Downstream distro, the stream is Debian → Ubuntu → Mint
Would it be a steep learning curve to switch to Fedora?
It depends on what you are doing on Mint and using the Mint or Debian specific features. If you have used apt, apt-get, dpkg commands in Mint, you need to learn the equivalent commands dnf, rpm in Fedora.
Would it be more or less time consuming than any extra configuration or troubleshooting involved in using Mint on FW?
I am a long term Fedora user and developer, and also was involved in Debian community, and used CentOS.
In my opinion, it’s important how easy to report and fix a trouble. The steps to fix it is different between upstream and downstream distros. I am biased. But if you want to fix or repair your software trouble communicating in a community by yourself like you did here, I would recommend the upstream disto like Fedora. If you want to use Linux disto as just a user, downstream distro might be good. But a small issue that you want to fix might not be fixed in a downstream distro. This is a downside of downstream distro and stability.
For people who prioritize the stability in Fedora, I would recommend using older stable version (the latest stable version Fedora N - (1 or 2)) than the latest stable version or development version called Fedora rawhide. That means continue to use Fedora 35 even after Fedora 36 or 37 will be released.
Is the experience between the two on FW significantly different?
We say maintained for ‘‘approximately 13 months’’ because the supported period for releases is dependent on the date the release under development goes final. As a result, ‘‘Release N’’ is supported until four weeks after the release of ‘‘Release N+2’’.
The commands to upgrade to Fedora N are always same and easy. Here are the commands.
