Even though I'm not the one being asked this question I'll respond, because why not
Personally I find most of contemporary aviation YouTube videos are a little annoying. They tend to be very self-aggrandizing and includes a lot of subtle flex.. like Stefan Drury, Niko Wings, Matt Guthmiller, CitationMax. They're all annoying and it seems their videos primarily cater to a non-pilot #Instagram! crowd
Paul Bertorelli, Aviation 101, Steveo, Fastback Flying, Blancolirio, Dan Gryder (if I'm in a masochistic mood).. those channels at least seem to have content directed more at pilots and have more technical or educational and interesting content (sometimes humorous), they are also a little less look-at-me!!!
.. I do believe this forum should have a YouTube subsection. The people who will give you flack simply won't click on it while the ones who are interested will go there.. win:win
