Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for data teams. S-tier if you already live in SQL + Python.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
