I mean, it was the world's first codified constitution, written after the world's first successful war of independence.

Which later constitutions do you grade higher? Who has stronger rights?

This is moving the goalposts, but I'll entertain this. What does the time / date of the original document have to do with the fact that it's rarely updated and that there's seemingly a constitutional crisis every week for the last year and a bit? No one is arguing here about the strength of rights or the 'grade' of the constitution.
