Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.A-tier for data teams. S-tier if you already live in SQL + Python.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
