For weird inputs I find DALL-E to be better, but both have failed at really specific stuff that I've tried to create as art. ie: a factory with human lungs.

With stable diffusion, it really creates some nice stuff for what is already available, like a pizza with specific toppings [0]. I've been using it to add pictures to any of the recipes that are added to my wiki site without a picture. I originally tried this with DALL-E with similar prompts and the results are less appetizing.
