I think they've all plateaued to a certain extent. There will be the regular numbers you get because you keep pretty faces around - there are more than enough attractive women always coming down the pipeline for that - but beyond that you need ideas and to work on the technical aspects. Bigg Jah is pretty much an ad platform for bluechew at this point(it must pay the bills, but the ideas are running short and it shows). Jamal just put out a vid saying he's done with content creation. Funarios is trying some Patreon thing that I'm not even bothering with, because it's just going to be an extension of "jump off the dresser" filler...they ran out of ideas a while ago. I don't watch all of the affiliated creators so I can't say which might be on the ball with theirs, but from what I've seen the only person who is consistently on their game is Jae the Fade. Consistently funny/ironic/satirical, eye candy never hurts but doesn't have to lean into it to prop up anything else that's lacking, comedic timing, editing, it's all there.
Working together and cross branding has carried them a lot further than most would have expected - surprise surprise - but the next steps will be the important ones to see them grow or not.
