A pub quizz would consider more than GCC and MSVC, and still I would bet many would fail if talking only about those two.

And I would double down on my bet regarding ISO C related questions, as I have met a few folks that contrary to myself as language nerd, hardly know what is written there or have even opened the PDF drafts at least once in their life.

A pub quiz isn't a developer, a codebase, nor an objective measure.

If you want to use your own head canon benchmarks to prove your obviously off-base point and tell yourself you're "correct", go for it.
