Nah, I go on all Warhammer Generals including /hhg/
and AoS definitely has the worst posters, there's occasional good discussion over there but it's got the absolute worst shitposting, bait-taking, and bait-posting. Mechanics wise AoS has probably become the best game but it's by a thin margin and honestly it might just be that it only seems good compared the garbage fire it was on release.
Lorewise I'd have to say I prefer 40k with 30k as the background lore, followed by Fantasy, with AoS being the bottom of the barrel of lore thanks again to the shitshow it was on release. Thankfully they got rid of Kirby and AoS lore has slowly improved.
But anyone who goes on all the generals will tell you, no matter what kind of shitposting we get here, AoS is worse. They're cunts about it too, blame every shitpost on Fantasy and say any shitposting done by them is a falseflag by Fantasy, but Fantasy players mostly just discuss their dudes and help new players try and figure out how to make models that aren't in production anymore.
Don't get me wrong, everyone gets shitposters and entire threads derailed, but AoS definitely has the absolute worst dedicated posters.
