Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
