Maybe it's just me but Illustrious MMMix checkpoint seem less photorealistic compared to Pony? But then I really like it. Pony often gave me like improper fingers, weird limbs, etc and fairly often wonky with ropes. But then what I'm genning probably may not fall into the /csdg/ category, unless I tinker further somewhere in the prompts later.

(Still trying out, so denoise increased to 0.9 but with tonnes of positive prompts to maintain as much of the original pic from img2img. But the clamps are clearer and improved)
