Sharing the workflow I used to make comparison I posted on <a rel="ugc" href="https://new.reddit.com/r/StableDiffusion/comments/1djkncw/give_me_a_good_prompt_pos_and_neg_and_wh_ratio/?utm_source=share&amp;utm_medium=web2x&amp;context=3">reddit</a>. It's quite demanding to do it all in one go. It works on a 4090 but might work on other GPU, IDK. You NEED to "unload the models" after each generation or else, in my PC, it fills the VRAM and will get stuck.<a target="_blank" rel="ugc" href="https://github.com/kijai/ComfyUI-LuminaWrapper">Lumina</a> is the most demanding. Even with the flash_attn installed. I get 2.5 it/s. It also don't accept a lot of resolutions.I won't write right now how to install, look at each respective GitHub page. But if anyone needs, I can assist in the comments.I updated the file with a more fixed version of the workflow. Now you can toggle what models you want to generate and the ones you don't.
