Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.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.A-tier for data teams. S-tier if you already live in SQL + Python.
