From my experiments it seems that SD XL understands prompts much better. While SD 1.5 is great at generating your typical "anime girl with big boobs" stuff - if you try to generate something a little bit more unusual - it usually doesn't generate exactly what you want and seems to straight up ignore large parts of the prompt.
SD XL seems to understand weird and unusual prompts a lot better.
SD XL is capable of generating 1024x1024 images without hacks like "hires fix". That's a very good thing, because hires fix sometimes introduces additional glitches while upscaling. Especially at higher denoising strength.
Hires fix fixed the broken face - yay, but the subject now has 3 legs instead of two. Things like that happen far less often with SD XL.

Pretty much experience with SD 1.5, but I'll give XL a try.
