Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
