Honestly I don't get why people use GenAI covers. You can get a surprisingly decent if basic cover for as little as $50 (lots of artists in Latam and SEA willing to work for not very much), and if you're willing to drop a couple hundred on it, great artists will make line up to work with you.

Considering the time and effort that goes into writing a book, if you value your own time, and work, this should be a no-brainer.
