I installed XL 7 today and I've enjoyed it so far. I went for the 32fp version. DreamShaper does a better job with facial variety; it's still my favorite for faces. But in most other ways I think I prefer CyberRealistic. It's certainly has more variety in body shape, and its sex pictures are better. Plus I like the vertical aspect ratio, which fits the game window nicely. I have not seen any red artifacts, but I haven't been looking for them.The images of women are attractive but with little facial variation, including with age. I tend to get Rebeccas who look younger than Gabrielles, etc. It reminds me a bit of the old Archie comics where Veronica and Betty had identical faces and bodies and only differed in hair and clothes. But you can fix some of that with the 'Append' fields in the UI. There's also an intermittent issue with red artifacts - random items of red clothing or sometimes even red skin - appearing on the images but it's not common. I haven't been able to find a negative prompt that eliminates it.
I haven't used XL 7 but it looks very similar from what I've seen posted. Can't speak for the pruned versions.
I have a minor question that probably relates more to the base game. Is there a RNG that generates the ethnic pool? I don't think I've seen any Asian characters at all in my play through, and I think I've met just one Latina. It'd be nice to see a bit more of both those categories.
