It's better in some ways than craiyon and worse in others from my sampling (craiyon seems to give me less 'nice' options but better logo-y images)
* $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?)
