ChatGPT produces the most comprehensive reports (17,000 words in one test), while Gemini creates well-structured 6,500-word analyses and Grok delivers concise 1,500-word summaries.

Gemini (8.5/10) offers the most balanced research experience, making it ideal for professional reports where methodology matters.

ChatGPT (8/10) excels in comprehensive depth but lacks speed, best suited for non-urgent academic or scientific exploration.
