It depends what VR PPD chart you use since most of them are off a little (quite a few of them only use HR/DF and don't take other factors into account, which is a little simplistic, tbh). Having said that, for sure 4K is a lot better visually than VR with regards to what you "see", but that quickly fades once the sense of space/depth takes over and immersion is greatly increased. Pick your poison!
One this is for sure, it sure is tough for me to use TrackIR after flying with a the G2 and even Rift S.
