One of the most popular comparisons on IT Central Station is Oracle Linux vs RHEL.
One user says about Oracle Linux, "We have no downtime for OS upgrades, hence customer production isn't affected, and we have no security breaches and higher performance of Oracle stack software due to its usage of Unbreakable Enterprise Kernel."
Another user says about RHEL, "[...] We have never, ever had any of our servers fail to function as needed. Red Hat Linux has given us five nines (99.999%) uptime for years.
In your experience, which is better and why?
