Correct, thank you Lorenzo!

Maybe the following is helpful:

Until quite recently the existing body of knowledge on the desription and measurement of democracy was somewhat hard to access. Fortunately, donors advised by https://legacies-now.de/en  and https://effektiv-spenden.org/ enabled https://ourworldindata.org/  to upgrade their democracy section.
Since August of 2022 the most important datasets can be accessed via the "Democracy Explorer" (scroll down on https://ourworldindata.org/democracy ). Hence, you can change the Dataset in display via the dropdown at the top left. Thus, one can choose between e.g., V-Dem, Polity, EIU etc.  and you don't have to go with V-Dem.

My take so far, from browisng myself and from talking to the team at OWiD is that, generally speaking, the datasets - provided by very different institutions and sets of people / authors from around the world - tend to converge on most key issues/ trends. (I haven't checked the conrete US example; there are literally millions of interesting specific data points to look at.)
