Kai's verdictA-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
