IME ChatGPT is pretty mid at search. Grok although significantly dumber, is really strong at diligently going through hundreds of search results, and is much more tuned to rely on search results instead of its internal knowledge (which depending on the case can be better or worse). It's the only situation where Grok is worth using IMO.

Gemini is really good with many topics. Vastly superior to ChatGPT for agronomy.

You should always use the best model for the job, not just stick to one.
