Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for open-source model APIs. The default in this space.
