I've used #MySQL before (last time was 2016, I think), but today I'm mostly onto #Postgres (and sometimes, #SQLite). I know PG is superior to MySQL is pretty much all aspect I could think of, but still, it seems that MySQL still has a quite big user base.

What's the catch? What am I missing here? Why would someone use MySQL over Postgres to build smt since Postgres [apparently] is better than MySQL in every single possible aspect?

It's a honest question. Please help me understand it – and perhaps, consider modern MySQL/MariaDB in next projects. :)
