A modern Linux with SELinux enabled (the default in e.g. Fedora) running apps inside rootless containers (Podman doesn’t even need a daemon) is likely much more secure than your default MacOS or Windows.
Well Linux powers just about all the most important systems in the world and SELinux was originally developed by the NSA, but I'd love to get your insights.
