Not necessarily. IMO a good model needs to follow your prompt well, and that was my problem with Stable Diffusion.
I've been trying to get a good portrait picture with "neon lights" on Stable Diffusion and it is almost impossible. Meanwhile with the new Dall-e, that was possible. The picture specially with SDXL is good, but it doesn't really have neon lights...
I tried now similar prompt on deepfloyd and managed to get there!
