Hey I just met you, and this is crazy. But here's my number, so call me maybe?

I’m a relatively new ComfyUI user and mostly work with the most popular SDXL models like Juggernaut XL, etc. But no matter how I set up my SDXL pipeline with Base + Refiner, I never get anywhere near the image quality you see from something like MidJourney or other high-end image generators. Is this a solid plan?
