One important way in which philosophical progress differs from scientific progress is that there’s much less consensus on what the data is or whether a theory fits it better, but I think this is mostly a function of most people being extremely philosophically confused, rather than e.g. philosophy being inherently subjective
I would say that it is a function of philosophy being circular: there isn’t a set of foundations that everyone agrees on, so any theory can be challenged by challenging its assumptions. Philosophical questions tend to be precisely the kind of difficult foundational issues that get kicked into philosophy from other disciplines.
