I've run thousands of prompts with DALL-E 2, thousands with Midjourney, and probably hundreds with Stable Diffusion.
My (very qualitative) feeling is that DALL-E 2 is good with composition and realism (e.g. generating photographs — you'll still get artefacts but it's less likely to look "computer graphics-y"), and is quite forgiving (you will usually end up with an image that makes sense).
Midjourney had a recent update and can now produce beautiful images with far more detail and realism than DALL-E 2 in some cases, especially for human and animal faces, but excels more on the computer art side of things. (Midjourney now has a community showcase gallery: https://www.midjourney.com/showcase/)
Stable Diffusion is a bit less forgiving than both, in my experience. Some people are able to create stunning images, but you have to invest more time into figuring out what works best.
I'm currently looking into taking images generated with DALL-E 2, then using them as a starting point for Stable Diffusion to add detail. It works partciualrly well for cartoon-style images.
You can see it significantly cleans up the artefacts the original DALL-E 2 image had. (Note: the original DALL-E 2 image is 1024 pixels square, but Stable Diffusion generated a 512 square output.)
Midjourney's recent upgrade was largely thanks to integration with Stable Diffusion. Somehow Midjourney's images still retain a more "premium" artistic feel to them though.
Great summary - just to add my 2 cents, I find Midjourney is far better than DALL-E 2 for creating 'artistic' / visually appealing images. DALL-E 2 actually struggles sometimes to be un-realistic, whereas MidJourney has no trouble being a bit weirder / out there.

For example:
- Original DALL-E 2 image of a horse in a city: https://i.imgur.com/CaNHHR7.jpeg
- That image used as a starting point for Stable Diffusion: https://i.imgur.com/EW1iKOO.png and https://i.imgur.com/VOQ35Oz.png
