I mean, if you want to convert normies, Hasan really is the ideal spokesman, he just strikes me as inauthentic at times, but that's probably because his content has some commercial considerations. Just seems like he's got the depth of someone who regurgitates ideas rather than synthesizes his own.
The biggest difference is that Hasan cash work as part of a leftward pipeline much more effectively than vaush because he isn't constantly punching left, and doesn't declare himself the be all end all of socialist thought. Vaush has idiotic takes-lots of people do- but he also has the affect of discouraging people from doing their own investigations of socialist theory and ideas.
