I think it depends.

I regularly ask both GPT and Gemini to give me options - programming libraries to do X, architecture suggestions, names for projects/services/classes

After they answer I ask each model what does it think of the other answer, and to give me a final suggestion considering both answers.

Both GPT and Gemini would frequently say "that other answer is much better than my one, it considered X factor that I missed".
