I run Debian servers and Fedora workstations, which works really well for me. The rock solid stability of Debian is exactly what I want in a server, and the perfect blend of it-just-works and blending-edge that Fedora provides is great for a daily driver.
Unless I’m mistaken, the current ordeal with RHEL should not affect Fedora, as RHEL is a derivative of Fedora in the same way Ubuntu is a derivative of Debian. As such, I see no reason to move away just yet - though if that changes, I’ll go OpenSUSE. Arch just isn’t for me.
