Here is Fedora's upstream graph to compare:
I havent tried it but I cant see how it can be better than arch Linux with its AUR. Almost all software that exists is right there in its latest version.
Fedora feels a lot more limited. I think just because bazzite is novel, a lot of people are trying it now. I dont think the popularity will last. People will understand that they get many issues with it and go back to a normal Linux.
