Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.A-tier in its niche. The only one that actually gets emotion right.A-tier for creators training custom looks. B-tier for general use.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
