Stable Diffusion vs Flux vs OmniGen vs SANA

A comparison between different free Text-to-Image models running on a local machine, covering Stable Diffusion (1.5, SDXL, 3.5), Flux.1 (Schnell, Dev), Omnigen and the new, super-fast SANA-model published by NVIDIA, rating their image-quality, prompt-adherence, speed and VRAM-requirements. I've tried to make the comparisons as fair and unbiased as possible, using the Google-Parti-Prompts method. So I created 1,391 images (107 per model) in 11 challenges and 12 categories and rated their quality. Still, it's a personal view but I will leave a link where you can download the rating sheets with all the images, so you can make your own decisions.
