How to get even a "quasi" objective view of quality OAIdeepresearch vs. Gemini

Why is DeepResearch from Google this much better than from OpenAI – we are in 2025 May and DR OAI "Agent" cant even get its own model correct.. It’s just a bunch of inaccuracies and irrelevance that are similar to example below why i qualitatively think gemini is going to win out.. I guess?? Unless below gap in quality is acceptable.. I dont think it is. The only main tool i guess it has is web search and it hasn’t figured out how to prioritize recent news when it comes to doing research …. Factoring and favoring more recent news and latest blogs is kind of a basic requirement for deep research for a ton of use cases unless im stupid .. compare snippets from research from both products.. Do we have resources where the latest versions are tested across a range of broadly useful cases and do side by side comparison to see which one is better - or some more quntiative benchmark that can somehow capture nuance of research output.
