Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
