Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
