At least on Nvidia, A1111 has had near identical performance to ComfyUI on SDXL and SD1.5 for me. Besides that, there were typical minor problems that happen when some guy's hobby project goes viral and suddenly is under massive scrutiny. It was the first "good enough" interface and now there is massive community inertia with extensions, plugins, etc. ComfyUI has found a place in the image pipeline design niche, but A1111 still seems like the best choice for new users who just want to spin up Stable Diffusion and generate some art for a D&D campaign or whatever.
