One example I'm familiar with which is different, are Schengen tourist visas. You need to leave before the visa expires. That's not the case for US tourist visas.

Apparently the Form I-94 (Arrival/Departure Record) card is phased out. But it used to be that it contained your allowed term of stay. I am sure the digital version has something like that. You do not automatically get the max allowed duration per your visa. It might be that they are one and the same especially short visa terms of course. But i haven't actually been since mid 2000s so I wouldn't actually know for sure.
