Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
