Easy. It's simpler to use.

Even to this day I still have to Google how to list the databases in PostgreSQL on the odd occasion I need to investigate something. In most other databases eg MySQL, MongoDB, Cassandra etc it's as simple as "show databases"

All you need to remember is "\?". There's also pgadmin.

Things you do more often seem easier.

nowhere near as intuitive as SHOW DATABASES.

It's not simpler. MySQL has much worse autocompletion and bizzare default behaviors. In comparision \dt is not that bad.
