MariaDB is not always a drop-in replacement. There's several features that MySQL has that MariaDB doesn't, especially related to the optimizer (for some types of queries, MySQL will give you a more optimized execution plan compared to MariaDB). It's also missing some newer data types, like JSON (which indexes the individual fields in JSON objects to make filtering on them more efficient).

MariaDB and MySQL are both fine. Even though MySQL doesn't receive as much development any more, it doesn't really need it. It works fine. If you want a better database system, switch to PostgreSQL, not MariaDB.
