Apparently XSO is better in general, just has more features and is nicer to use. Probably performant too but who knows.

No, because you can still get it off Github and install/use it separately. Can't do that with XSOverlay.
I'd also love to be able to see the source code after buying it (OVR Advanced Settings is open source and XSO isn't). I'm a tinkerer at heart, and even the slightest things would annoy me a lot if I can't tweak them myself.

I'm very tempted to just write my own open-source overlay app in Unity.
