I've been using Midjourney [1] (it's not free, 25 photos demo, then 10$ for ~200 photos or 30$ for unlimited I think?). It's fairly fast, ~20s for a grid of 4, then as much for upscaling. I like the controls, it lets you do variations and tweak the image as you go.
It's not as good for doing concrete asks, but it's very good for getting specific vibes.

* $10 for ~200 prompts
* $30 for ~900 prompts + unlimited "slow" prompts where your job is put at the end of the queue and you have to wait longer (no idea how much longer though.. are we talking about seconds or hours here?)
The whole thing is run through Discord bot, which is unfortunate but I guess it allowed them to get half their infrastructure for free? You interact with the bot through Discord commands and it generates and returns the photos to you.
It is kind of annoying but lurking and seeing other people's pictures is nearly as enjoyable as making your own. Plus you can use the bot in your dms if you'd like to keep them private.
In a way it makes sense. Discord provides the UI and authentication infrastructure, so the Midjourney devs only have to worry about the actual functionality.
I immediately subscribed to Midjourney after seeing a couple of online tutorials. Prompts/commands being all open source on the community feed was the killer feature for me.
