DAZ might get you on Steam, but it costs more money to build an asset library, and with that comes financial risks.
Also, DAZ has even more UI problems than Studio Neo (The HS studio engine), is a bastard to work in, and with all of this you end up with girls that look like Barbies, and guys who look like Kens. I am of the same opinion as Caribdis, I don't like DAZ in any way. HS2 sucks, but DAZ is worse, more expensive, and produces a look I find ugly.
Edit: Oh, and to make matters worse, DAZ is so inefficient at rendering (because IRay is awful) that it requires additional beefy PCs for producing images and animations. With studio Neo, 4k renders (even with character skins modded into infinity), take no more than ten seconds, and 4k animations are only a few minutes per second (second edit: On an RTX 3070, it'll obviously be worse on lower end hardware, not that the 3070 is holding up very well right now).
As such, you can see why someone would prefer to "busk" in Studio Neo, than "sell" in DAZ with all the risks and expenses.
Ideally we would all work in blender, but the character and environment creation issue (i.e the time it takes - weeks instead of hours, per character - along with the expense) make this impossible until AI prompt modelling gets a little better. Which I am hoping happens in the two and a half years my Honey Select 2 project will take to complete.
