I don't want to pick on Ubuntu itself but given your requirements (>= 5y support), I don't think even Ubuntu LTS is suitable as a desktop system.
While Ubuntu LTS is support for five years, this holds only true for a subset of the packages - the "server" ones. "Desktop" packages are only support for three years: https://wiki.ubuntu.com/LTS
