Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
