Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
