Quest 2. I don't imagine that i see all of the advantages of 120fps file played on this headset. But I have changed my DeoVR settings to play 120fps and I download and watch 120fps files on Heresphere.
If i would have a better hesdset then maybe results would be even better (I just assume because i haven't used better headsets than quest 2).
What I can say for sure is that image quality is better on quest 2 with 120fps file.
I imagine that it may be like watching a 4k movie on a fullhd tv. Movie still looks better than a full hd copy but it is not as good as 4k movie played on 4k tv.
