The only 2 youtubers I like are Baldemort and Amber king. Sometimes Arch, but not necessary his 40k stuff.
Most youtubers either just "voicover lexicanum/w40wiki" like Luetin, which is fine, but I can read, or put their own retard spin on it like Majorkill, or just drool at GW like others etc.
Baldemort is an old guy just drooling over stuff like a kid at Christmas, basically same grognard as Arch but less bitching more "melty melty goes boom so cool" and he says he just does what he likes.
Amber king does 3 hour long character deepdives mostly on primarchs.
Blacklibrary is a Pajeet who does ask weird theories and generally acts like Alex Jones for the hobby. Whacky but with an odd perspective unlike lets say Major's tired contrarian dudebro antics And complain that GW haven't updated eldar in ages.
Wolf Lord Rho I haven't seen much of so no complaints there, I just don't know.
Swtor Trailer was good, but please don't bring up the Ultramarines Movie. It is bad even for Abnett and its like the Ewok Movies and Christmas special rolled into one Dan Autistnett idiocracy.
He doesn't know space marines got nightvision in helmets....
