I've only started generating AI art about a month ago, so I'm really no good at judging general model quality, but this thread convinced me to give Illustrious a try (well, SmoothFT anyway), with this Shiori test set. I'll need more time to figure it out, and the model itself appears to be on the rough side, but it's looking promising so far!
