Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier in its niche. The only one that actually gets emotion right.
