Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
