I usually watch what's being recommended, which is related to my searches in some capacity. Because of this I end up watching videos from some of the most popular RE YouTubers, which is Residence of Evil, Ink Ribbon, Sphere Hunter, and AvalancheReviews. Out of those four, I think Ink Ribbon and Sphere Hunter are the most interesting and likeable, with the best factual reporting. Residence of Evil seem to be resorting to rumors and fan-made content a bit too much for my taste, and AvalancheReviews is a biased RE2 fanboy who's never satisfied with anything unless it's RE2. I also lost some respect for AvalanceReviews after he presented false facts about the Silent Hill series.
I agree with you a lot on Avalanche Reviews. He has such a narrow concept of what Resident Evil is for him, and everyone else is obviously wrong, because he acts like he's the only one who truly knows what Survival horror is, as a concept and as a genre. I used to like his takes sometimes, but I also catch myself rolling my eyes so hard at some of the things he says that I get tired of watching him. I hate terms like "true survival horror", and "true resident evil", and that's something he does a lot. I also agree that Residence of Evil spends way too much time talking about rumours, but I discovered some very fun mods through his channel, like the Barry's mod for RE1, the Marvin mod for RE2 and the Ada mod for RE1, all very crafty and very fun.
I also watch Ink Ribbon's videos too. He seems like a pretty nice guy, very likeable and his content is always interesting. I also dig Sphere Hunter, even though I tend to disagree with a lot of her opinions, but the in depth work she does to make her videos are really commendable. We might disagree, but that's what opinions are for. She does a great job.
As for let's plays, I like to watch Gab Smolders (she used to go as Girlgamer Gab) playthoughs. She's an horror fan and, as a consequence, she played pretty much all of the RE's (some of them more than once on her channel) and she seems like a very likeable, easy going person. Also, she slayed playing Alien Isolation on the hardest difficulty...something I haven't done.....yet. hahahahaha!
