Fedora Workstation: User friendly and easy to setup

Our take
Fedora Workstation is the sensible default for someone leaving Windows or macOS who wants a modern, well-maintained Linux without the babysitting, and it ships current software with sane privacy defaults. It is a general-purpose desktop OS, not a hardened anonymity system, so it raises your baseline rather than protecting you against a serious adversary. Pick it as an everyday daily driver; if you need real anonymity, that is a different tool entirely.
