I run stable-diffusion on my own hardware so I don't have to worry about subscriptions or waiting for heavy usage. The RTX 3060 keeps up pretty well and I will probably add one more to speed things up a bit. I can generate thousands of different images in a day with my setup. I am reading about training my own images and importing it as a style. I think it would be pretty cool to be able to import all your own photos and make original content from that.
