Yeah boost is definitely good, it was my main app until a few months ago. Recently I have been trying Connect, which is another great app.
Connect has improved a lot since I first tried it, also doesn’t have any ads. But all things considered - Boost is bit more polished than connect.
It’s been just over a month using Fedora silverblue (Ublue ) for me and the experience has been pretty good.
What I do is just setup a distrobox container with the arch image and install software using paru from AUR. So far this workflow has been working really well. for me.
Also if you decide to use any Ublue spin, you’ll also get homebrew pre-installed. So that can also be considered as an alternative option to AUR.
