So it's essentially your gut feeling? It's obviously going to be hard to determine a number for a statistic like "most popular", and there are always very different interpretations of the available numbers, ending up with vastly different rankings. I.e. this one keeps Oracle DB at place 1, mysql at second: https://db-engines.com/en/ranking https://db-engines.com/en/ranking It links to their method at the top of the statistics. (Oracle has basically a DB monopoly if you believe that ranking, as these are both owned by them) It's dataset is probably flawed, but I think we can say "Rumors of mysqls death have been greatly exaggerated"
