I don't especially trust renderhub. Some of the stuff I've got from there is set up strangely, missing obvious things like the 90px icons that show up in the item queue in DS, their prices are higher, and their free section is becoming sort of a cesspool of crap. Even before CGShare died, they had more than their fair share of game rips and editorial licensed stuff. It all makes me hesitant to shop there. I'm sure I'm not the only one. 

Also, a long-time Daz PA told me a while ago how the money situation is for them. They described Rendo here as hobby money and Daz as a place that allows them to earn a living, own a house, a car, etc. Other PAs seem just as loyal and committed to selling on Daz site.

I know some current and former PAs are not as rosy about selling on Daz site. Even so, I have not heard any tales of folks earning their fortunes on renderhub. Not saying it's not happened, just saying I've got no evidence to confirm or deny the notion.
