For the most part, I don't watch livestreams, I just watch the occasional video on youtube when I have time. There is one twitch streamer whose reviews I trust, and that would be CohhCarnage
The first video I ever watched of his, was Divinity Original Sin 2 back in 2017. After watching his playthoughs, I bought the game to play myself and I loved it. In 2017, I didn't even know what a CRPG was. I love his playstyle, which is meticulously slow, combs through everything, hoarding loot goblin, looks for secrets everywhere, reads everything and plays on hardest difficulty. This is how I normally play, so I appreciate that he delves into the lore and gives all games and devs adequate time. I also appreciate that when he doesn't enjoy something, he just says "This is not for me," or "this game is very niche and would appeal to X kind of player." I appreciate that he realizes not everyone is going to love every genre, but you can still be respectful towards people who do enjoy the game. I love that his community is very kind and welcoming, and NON-TOXIC.
With BG3, I didn't follow the early access because originally Larian said they would not be coming to console. I was really sad about that, but I just told myself I'd watch Cohh play and that's that. When they announced the game would be coming out on PS5, I literally went out and bought a console JUST for this game, and I've loved every minute that I played.
With Cohh, I think the only things I need to hear, are if he says the words "This game is special." I think 90% of the suggestions he has given, and I have purchased, I really enjoyed.
