For bland stock photos and other "general-purpose" image generation, DALLE-2/Bing/Adobe etc are... the okayest. SD (with just standard model weights) is particularly weak here because of the small model size.
If you want to get arty, then state of the art for out-of-the-box typing in a prompt and clicking "generate" is probably MidJourney.
But if you're willing to spend some more time playing around with the open-source tooling, community finetunes, model augmentations (LyCORIS, etc), SD is probably going to get you the farthest.

By sheer number of image generations? Take a guess...
