Money≠quality. You can easily see the difference between the two threads in not only reviews, but general attitude. As for why it makes more I would say its primarily 2 reasons, Marketing, and the NTR community. First one doesn't need to be explained, the second does. The NTR community, while being home to one of the most divisive fetishes, is also one of the most dedicated. They will attach themselves to any game because they don't have a lot of games that cater to their fetish, as opposed to something like incest which there's A LOT of games for.
Which leads me to this, while a lot of the NTR community will support you almost no matter what, because of how NTR works and how divisive it is, its going to turn off a lot of potential Patreons. Even if its made 100% optional a lot people will see that it has NTR and walk away right there, so the there will be a wall he wont be able to cross eventually. This is the situation Seeds of Chaos have found themselves in, they make a absolutely great job at everything in the game, from CG to writing, but they've hit this wall.
