I think the main difference between OSS like Blender and the competition is it seems like OSS only gets better. Each version is a little bit better, so projects that were once not competitive catch up. Blender is an obvious example, but also look at Krita, or the entire KDE project. These pieces of software age like fine wine: they get more features, they get faster, and they get more stable.
Closed-source software seems to get... stuck. In the best case. Often, they regress: becoming buggier from version to version with less features. I think of Windows and the entire Microsoft suite of applications.
I think one exception is Gnome. Gnome loves removing features more than they love not implementing popular Wayland protocols.
