Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier for data teams. S-tier if you already live in SQL + Python.
