Here are some small ones I like that i think haven't been mentioned here:
Craftdwarf -
https://www.youtube.com/channel/UCMG_DhlUf6UXgSaFfS6JD1gOne of those catch-all anitubers a la MothersBasement but with actual founded opinions. Nothing spectacular but its good for when you have nothing else to watch
Donghua Reviews -
https://www.youtube.com/channel/UCvaePYBLM8cgoNUGwBszF4gFor your donghua aka Chinese anime needs. Content-wise its no different than 90% of anitubers but hes one of the few ones covering Donghua shows
E-Kon -
https://www.youtube.com/channel/UC4mBmLO9n2VLjfod0fJUsPQHalf dead channel but with potential so its worth keeping an eye on for when he uploads, personally I like his narrative style
Ember Reviews -
https://www.youtube.com/channel/UCJek2V5GyvHLtR_nUWTeEWQHe's really knowledgeable about anime and it shows in his analysis. His style is really accessible I have no idea how he hasn't blow up yet
GilLIesHere -
https://www.youtube.com/channel/UCmbRnJ1aKK3U9r_6sufdWJQNot really an anituber but their AMVs are pretty cool and need more love
Jackisboy -
https://www.youtube.com/channel/UChPSzrw4gma3uQOQoAIrrzwA kind of retarded random humor channel and unironically one of the best
Kor -
https://www.youtube.com/channel/UCZ0tT9YPiE4AJCGMVARyxSwSpecially useful for his analysis of rare shows, shorts, animators, etc with unique styles that he conveys well in his vids and if you share his taste its a plus. His other videos on music or year-reviews are worth checking out too
ManMode -
https://www.youtube.com/channel/UC9v_sym6MIIWqWg34DCJjagGuy's probably dead by now but his uploaded vids are worth the watch and bring up elaborate points, something rare to see these days
Shabu That Music Nerd -
https://www.youtube.com/channel/UC0W5pGnPDWL00d9tua138XwFor the interested in anime music and OSTs as he focuses on them
UrbanTheMyth -
https://www.youtube.com/channel/UCG7U0QAqTTgPaF8cv8kVJoQAnother half dead channel but has potential and a distinct style. Also he does nice AMVs
Zeria -
https://www.youtube.com/c/ZeriaYT/videosProbably you already know her for her videos on marxism or postmodernism or general leftist things, and if not I recommend her channel to anyone who uses this site. Her academic style is really appealing.

https://www.youtube.com/channel/UCxl7Nnf-70xG4zkcGLivTzA/videosOne that has come up in the past year. Solid content and keeps you engaged well
