So you will have to emulate all this apps? Like I’m not talking about these on the play store like games or others, I’m talking about the great apps that you can find on fdroid
That’s really depending on your use cases, for example if I want to install distro for my grandma use Mint, for a graphic guy (as in this example) use Arch or Fedora (or even OpenSUSE), etc.
If you use Fedora and only FLOSS apps on your PC that’s great! Next that’s the turn of your phone, at the end you should use only FLOSS apps, first try to switch from FB messenger (switching to SimpleX), next don’t use spotify : cracked Spotify (not for privacy) or RiMusic for no-ads and privacy. For maps there’s no real great apps but maybe Organics Maps for navigation and GMaps WV to see the infos directly for maps but securely. For your bank, I have no real idea, you should remove it but if you can’t… Or you have others choice for your OS, maybe your banking app will work. You can useDivestOS or CalyxOS but for privacy in fact /e/OS is even better than Graphene (not for security, for privacy).
I’m sure talking about the 30days challenge from Raid Owl and I have an idea of his conclusion. First he’s a power user (not in the fact of tweaking and scratch in the file system), he needs a lot of stuff to work. And for someone outside of the traditional office work or maybe developing, Linux is hard to use for graphics works, so sure Linux Mint is not for this kind of people but you should always recommended it to “normal” people and beginner in Linux. Sure in this case his conclusion is wrong, he should have used Fedora, Arch or OpenSUSE, but that’s it.
