AlmaLinux vs Rocky Linux
AlmaLinux vs Rocky Linux: does the choice matter?
Both are free rebuilds of Red Hat Enterprise Linux, both offer roughly ten years of support per major release, and both are binary-compatible with RHEL. In practice they are interchangeable. AlmaLinux has moved towards ABI compatibility rather than strict bug-for-bug parity, which lets it ship some fixes sooner; Rocky holds closer to upstream. Pick whichever your vendor documents.
