This dude got really good sense of humour and puts insane effort into his comedy videos and also travel vlogs from the most exotic countries you can imagine.
He made parody of Casey Neistat (https://www.youtube.com/watch?v=VlDdzXI-KTg) which was so good, that even he had only 100k subs back then, Casey shared it himself and even made cameo in the sequel (https://www.youtube.com/watch?v=Jb8uinZqNWg). Currently he is doing quite popular series called Best (and Worst) Reviewed in Eastern Europe, where he goes to various restaurants, hotels, bars and try to be as annoying customer as possible, which often results in hilarious situations (https://www.youtube.com/watch?v=TFkF99oaioI)

Music theory and other music topics

I strongly recommend his videos on the fastest/slowest/hardest music, he gets into the psychology of perception, philosophy of art, and history of music

chess24 en espaƱol - I love chess commentary/banter blitz on St Louis Chess Club, chess24, Chess.com ES, etc but this is my favourite, especially anything with Divis and/or David Anton and David LariƱo is a joy to watch. They play brilliant attacking chess and laugh a lot; excellent commentators too. Also it's good for my spanish!
He recently cracked the 1 million subscribers line but I think he is worth mentioned. I love his Commodore Series, which is very informative if you into this stuff. Also he is a humble guy, no 'Like&Sub' and other stupid catch-phrase, just good informative content with heart and soul.
