Heres the ones i usually watch
G&A reviews-mainly for his servant reviews there a good help when it comes to what the game plan is for servants.
TouhouSniper98 -i like his reviews aswell their entertaining and while less frequent its usually a good idea to check what other people think of servants.
Voice of Saint Quartz- i like his scripted content and hes pretty entertaining aswell also some of his discussions on JP servants also isnt half bad
Honako Green- i like watching solo videos and honako provides them in spades.
Plushie Mistress-Similar with honako except with more carmilla involved.
Forgot about him but Fino plays is also pretty good content wise.
