Yeah, I think we are pretty past an idea of "better" and are at the point where it needs qualification as "better at". "Claude writes, Codex reviews, and Gemini doesn't get installed" is my go-to, although I go to Gemini whenever I want an advanced graphical calculator, or data extraction of any type.
"Gemini researches" has been my go-to for awhile (although GPT seems to have gotten better recently in this category?).
Essentially, I use it when I truly only need an "Advanced Google" to find lots of document or website references based on only some partial understanding of "X". I don't like having it do anything with those things. Only when I need to find those things.
Claude, especially, seems to absolutely hate doing research when there are major ambiguities in your question. It's the only one of the major models that keeps playing 20 questions with me when I neither know nor care what the answers to those questions are.
Mostly my experience, but “Gemini crunches data” would be my replacement there.
If I have a task that requires parsing through swathes of irregular data that traditional ml would choke on (or require an intermediate training step ala bigquery), I have gotten much better results from Gemini than the other two.
