European here, I don't visualize a day as two 12-hour parts, so each of the twenty four hours has its own unique identity (00:00 - 24:00) in my head.
Reading time in AM and PM takes me a bit longer to comprehend.
I also find analgoue (12h) clocks harder to read than digital 24:00 ones.
I'm learning Japanese rn and they have that AM/PM thing going too. Very annoying.
