Criticism on Stoper workflow, communication and quantity produces per month can be acceptable, but associating render quality of DPC to Stoper is an insult to people with functioning eyesight. If you say DPC characters look more real, where most of them are cartoonish: Isabella proportions are real?; Riona (eyes are so big compared to her head); Maya (a wig for hair, horrible skin, fake boobs); Jill (proportions, goblin smile, porcelain teeth); MC's cock; Sage changing face; all the feminist girls are fat and ugly and so on. Yeah, Sarah's body is realistic, that' one.
Not even talking about clothes or how bodies are posed, deformed legs (common DAZ problem) and such.
DPC focuses on quantity, he produces loads of average renderings. He does not have the time to polish each image. I really like Being a DIK but I'm not blind.
I disagree on the last part, it's simply a false statement. DPC has produced probably the best overall VN, but he just can't reach a high quality in renderings and never did approach the level of Stoper. DPC just uses DAZ for his renderings, and that's it. He also does not care to improve his quality to Stoper's level, as you wrote, "DPC cuts corners" and that's a savy choice for his business. Stoper is an excellent artist but from a business perspective DPC could teach him all the day and Stoper should just stay silent and learn.

They have an opposite approach, Stoper aims for perfection in each rendering, all the other aspects are secondary. DPC has a clear global vision of his project and a constant focus on his cash-flow. Stoper releases his game for free, DPC bans from Patreon/Discord if you only dare to say you used a mod or express a fair critique. With their current VNs, DPC made millions of euro, Stoper makes 1600 EUR/month.
They are two so distant and diverging approaches to VN, if feels just wrong to compare them.
Do you want to change Stoper's approach? Yeah, good luck with that.
