As a Youtuber: He's kind of bad. His recording equipment is subpar at best. He picks up way to much room noise for me to find it enjoyable. Anytime you actually see him, he looks like he's doing it because he's forced to, and frankly, it sounds like it too. Extremely unenthused.
As a Pokemon fan, I find his "trivia" interesting, but for the most part I find myself disagreeing with him way too much on his opinion videos. Like, for example, some of my most hated mons are his favorites, and vice versa.
I don't watch him but rarely, though I reckon I could see why people would.
