I have been pleasantly surprised by Airbrush. The image quality is very good with the right prompts.

There are a number of these AI Art Apps around but Airbrush offers you two separate options, Stable Diffusion and Dalle-2 and this makes it a unique proposition at a great entry price. Really hope the updates to the newest versions of Dalle will also be included.

The other thing I really like is that the Founder is extremely active here on Appsumo and this gives you a lot of confidence in the future of the project in what is a very crowded field, and one that will only get more competitive.

I especially love the ability to download images similar to the ones you are looking to create from the public pool, which doesn't cost any credits. This is one to watch.
