Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier for designer-led sites. S-tier if animations matter.S-tier for model-shopping. I use this for every prototype before committing.
