Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for teachers. If you teach K-12, start here this week.A-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
