There are a few improvements in Aurora over Silverblue that you might like.
It ships with homebrew which is perfect for CLI tools.
It ships with distrobox instead of toolbx which is much better. You can install any distro while toolbx is just a Fedora. For example I’m using Arch in toolbox because of the number of packages and the fact that they’re usually up to date (no need to wait for a major release).
So far I never had to use rpm-ostree, and for VSCode I use distrobox precisely because of the permissions.
