The models' case: Strongest agentic coder in practice — top-tier model quality (Opus/Sonnet 4.5-class) plus a mature harness (subagents, hooks, MCP, headless/CI use) that reliably. The models' main caveat: Terminal-first and token-hungry — heavy users hit real cost/usage limits, and devs who want a visual, point-and-click IDE experience should look. The strongest alternative is Cursor — Best overall daily-driver balance: excellent repository context, fast completions, capable multi-file agents, strong diff review, and access to. Not unanimous: ChatGPT picks Cursor; Gemini picks Cursor.
