hmmmm I almost exclusively watch Youtube so I will put some of my regulars here with a focus on more positive non-toxic people for you guys in no particular order. they will be a bit reductive for brevity:

Day[9] - top of the list because he seems very well tuned towards what you wrote. a looooooooong time (like 15 years now ?!??) twitch variety gaming streamer, uploads full streams a lot. He constantly takes breaks for long winded rants about game design but honest to god the mans brain is a treasure, the videos always entertain through humor or learning, and ive been watching the guy since justin.tv, so let me tell you he is one of the very few genuinely good people in the space, especially for this long.

Funhaus - mostly tightly edited, almost all comedy focused, and while they use games as a bouncing board for the comedy theyre not often the actual focus of the videos. The cast has rotated through the years for many good reasons, causing changes in humor style but every person on the channel is still extremely funny with a tremendous group chemistry. another 10 year follow for me (if you include inside gaming) which leads me to

Inside Games - mostly focused on gaming news, and LEGIT gaming journalism, with deep dives and fun clown math. This is founded and headed by two of the former Funhaus members who left to return to their roots of the similarly named Inside Gaming, which predates Funhaus. Confusing, i know, but what you need to know is that you can get really concise, funny, good, non-toxic 'Gamer' news about gaming here weekly.

Alanah Games - mixed variety of content, but all focused on gaming. More deep looks at news articles, amazing interviews with voice actors. Alanah was a games journalist and writer for a long time, has a ton of experience and connections, and maintains a positive attitude the whole time. Really smart, and while i dont watch every video, there are definitely a lot that are worth watching. also yes, former Funhaus if you can detect a pattern.

Videogamedunkey - not very positive/non toxic and has had his controversies, but he does always put out very funny gaming content so he deserves a shout out.

Pestily - nearly exclusive tarkov streamer, but he has been branching out to very fun IRL content recently. If you have a mild interest in watching first person shooters, or have played/ do play Escape From Tarkov, hes simply the best for that. Easy to get overwhelmed with how much he uploads across all of his channels but if you can deal with that he is a genuinely good guy with fun interesting content on the regular.

Settled - if you have a mild interest in runescape or have played it extensively, Settled is a wholesome positive guy who plays runescape with truly deranged and extreme restrictions, making every video a true feat of human willpower. He is amazing at explaining things and very funny imo.

Dead or borderline dead channels with an amazing catalog::

Mans1ay3r- very very funny edited voice lines from video games, with manually rigged ragdolls.

Sovietwomble - he uploads so infrequently this is where he lives in my brain. But very funny well edited group gaming content.

Mr. Sark - super funny group content, less tightly edited that womble and never uploads anymore, but ill be damned if i havent watched every single video a few times. Sark is just a good funny neat dude.

Charborg - a lot more niche than the rest here, but Charborg has some true blue insane creative funny stuff. lots of pranks, weird roleplay, garbage garrys mod maps and roblox and Vr chat. a real underbelly of the internet stuff, without getting into the hateful areas.

DanielSL - apparently he streams a lot, but his YT is mostly dead. one of the greatest of all time trolls. calm, never breaks character, devious beyond imagination. He always gets his mark, and his power over other people scares me a bit. Riveting videos, top to bottom in the catalog.
