Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier infrastructure. The one platform every AI dev eventually uses.
