That's not an adequate comparison. You're comparing one simple solution to one complex solution. The actual comparison is one complex solution to several thousand simple solutions. What you're comparing is running oracle on a grid of mainframes using some esoteric programming language compared to running about 2,500 MariaDB servers (based on comparisons of modern wind turbines to modern nuclear generators). Oh, and that's just for one site. So you can manage a couple hundred unwieldy Oracle servers, or a quarter million MariaDB servers.
