As far as i am aware.. online courses which offer u certificates after u pay are no more given the recognition it deserves, as it used to be popular back then...
These days skills are the most important thing nd it doest matter where u learn either by watching YT or some courses or reading... At the end the question u have to ask are u well equipped with the expertise in the domain which u are interested in..
Comeing to Courses that I highly recommend depends on ur interests : )
