Do not pollute your mind with questions, comparisons, opinions and speculation.
A student is not capable of assessing the skill of the instructor or the art itself.
They see only what they are exposed to (the beginners syllabus) and draw knowledge from their own minds.
Your values and insights are based on your own education, experience and criteria.
Upon what you can see and what you consider to be important.
Given that you do not possess any real skills yourself and have no experience to speak of... are you equipped to make any worthwhile assessment concerning the art?
