I'm always impressed by how much super sampling upgrade my old VR headset's display's image quality. I think it's mainly because constant small head movements amplify aliasing, so I tried to make a simple visualisation (made with AI) that simulate looking in VR at the same super sampled and non super sampled subject to try to show how it can be important :

Anyway, I think it makes the environment much more real and I think that is a parameter you should try to dial up before thinking of upgrading the clarity of your experience with new hardware.
