Benchmarks tell you which model scores higher. They do not say which one handles the document on your desk.
Take one real file from your work and give ChatGPT and Gemini the same instruction. Compare where the answers split, not which one wins. One model may restructure your text; the other may keep your wording and add missing context. That difference decides which tool fits this task.

Run the same test on a second file type before you decide. A contract, a spreadsheet export, and a design brief rarely split the same way, so one result is not enough. Keep a short note of the model, the file type, and the difference you saw.
