What you will learn

Direct comparison: same prompt, both tools, real-world test. Mike finds out which tool performs better at structured web research.

Result

Gemini wins clearly. Faster, more structured, more sources (211 vs. 48), better-presented results. Direct export to Google Docs.

What Gemini does better

• Shows a customisable research plan upfront

• Gives a time estimate (1 / 5 / 10 minutes)

• Works methodically: first an overview of all sports associations, then prioritises, then works through them one by one

• Shows each jump in reasoning and contradictions transparently

• Delivers the result directly as a Google Doc with all source references

What ChatGPT does less well

• Went straight to the football association instead of first researching an overview of all relevant associations

• Only 48 sources vs. 211 for Gemini

• ~14 minutes waiting time vs. a few minutes with Gemini

• Less transparent reasoning
