Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for model-shopping. I use this for every prototype before committing.S-tier for designers. The only one that takes vectors seriously.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
