I will say, as opinionated as this statement is, I like that you actually give your legitimate reasons. Personally I know there are many artists I like where - if you asked me to tell you why I think they're so amazing, I would just end up listing reasons that I personally like them, or just how I feel when listening to their music.
This seems like an odd thing for me to say under what seems like such a subjective and opinion-centric post, but I like how you aim for relative objectivity with your reasoning. You talk about Tyler's diverse list of influences, his unique style of production - I don't even listen to Tyler, The Creator but honestly you make a pretty good case.
All of that being said, I think this post still leans a bit more to the side of opinion rather than fact.
