i believe explicit inner join will be faster since in that case mysql doesn’t find the type of join. otherwise it will fetch all the records from both the tables and display it to user.

SELECT *
FROM employee
INNER JOIN department
ON employee.DepartmentID = department.DepartmentID
Example of an implicit inner join:
SELECT *
FROM employee, department
WHERE employee.DepartmentID = department.DepartmentID
Explicit is given the more performace when the query is where complex with so many table. & so many where condition..
