Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier for creators training custom looks. B-tier for general use.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.
