Though I don't watch all of these channels often:

TheClick, Jammidodger, OneTopic, The Queer Kiwi, Conure, Zeltik, Dr.Wily, ZeldaMaster, PBG, Flamingo, DanTDM, Pecos Hank (and some other tornado related channels), ManlyBadassHero, GooseBoose...

Thene there's a couple of smaller channels I've like just because they discussed videogame horror related stuff. A recent one was LowPolyLevi. Anyone who decides to yap about niche horror media or creepy easter eggs in videogames gets my attention. :)
