I think it’s a reinforcing cycle. (I) Debian gets recommended less often for home use -> (II) less people become proficient in it -> (I)

what does immutable in this context mean? I am guessing you can still install software on bazzite

No worries. While the distro matters and some distros have more support than others, whether your software runs on Linux will often be a distro-unrelated question. While some applications don’t run natively, many (not all) are executable through a compatibility layer like Wine (which sounds fancy, but comes with little additional effort for you).

Don’t be afraid to test a boot usb with liveboot (testing the OS without installing it) and see if you can make your software work - just don’t be discouraged if it lags a little as larger liveboots are not intended for larger software installations, I think.

Heyho, maybe give us some more info. Right now I would say watch a video that showcases Ubuntu, Xubuntu, Mint and Fedora.

Very short videos but I am sure they help getting an intuition of what suits you best :)

Be aware that you can try them out via a boot usb without installing them to have a closer look before committing.
