I’ve got a tendency not to use AI art generators that I can’t run locally, but I do remember Bing being good when I tried it previously.
As far as Pony v7 goes, that’s being trained on a different model, AuraFlow.

There’s an interview from a few weeks ago here:

Illustrious XL is more of a new XL based anime base model competing with pony. If you are generating anime/furry pictures, it might be interesting, and it seems to be big, but from what I remember, it didn’t do that well with ponies when I tried it, though I should give it another go. (SeaArt Furry XL can do ponies, IIRC.)
