Ubuntu has 5 years of “standard support”, with EOL after 10 years. RHEL has 10 years of “production”, with another 3-5 years of “extended support”.
Edit: I'm talking about Ubuntu Pro that is 10 years.
RHEL competitor in the market is Windows, not half supported hobby distros.
I myself only switched (to CentOS Stream 9) last February for my personal servers.
