It's free, it's open source, you can customize it and it won't micro manage you with content. Midjourney said it wasn't pg13 when I tried to do

If all you want is a one-off picture, stable diffusion is great. It's very easy to generate something that'll make you go "I'd print this and hang it on my wall"

SDXL is slow to achieve good results, like on a 4090 i can get 35-40 it/s on SD 1.5 but SDXL @ 680x1024 res i'll get about 5 it/s. Even @ 8 times slower, i still wouldnt hesitate to use SDXL over SD 1.5.

No one wants to pay to use base SD, the base model sucks. People like the fact that it's free, unlocked and customizable. It's the community around SD that is
