`SELECT <columns> FROM A, B WHERE <condition>` instead of `SELECT <columns> FROM A JOIN B ON <condition>` to join tables?


I think it is more prone to result in full cartesian product if we forget the `WHERE` clause and it will result in duplicate condition columns when using `SELECT *`. Is there any advantage over using `JOIN ON`?
