Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. Bet on this one — the Sparkpage format is genuinely new.
