I'm not the parent commenter, but I use a Dygma Raise (60% split kb). It has some issues but navigation hasn't been a problem. I use two of the thumb buttons as momentary (push-and-hold) layer shifts, with hjkl (and asdf) becoming arrow keys as long as that navigation layer is active, and qerf/yuio becoming home/end/pgup/pgdown in that navigation layer.
Unlike some of the other people listing VR headsets, I actually use VR regularly. But the Vive in particular was an expensive piece of junk: it lasted not even a year before one of the displays started to die, then experienced the same failure again 6-7 months after warranty repairs. Apparently this failure mode is common.
In general I think it's best to stay away from the high-end headsets: HTC, Varjo, Pimax, Bigscreen, everyone I know with them has experienced problems of some sort or other. Many of the midrange headsets are worse on paper, but seem to have fewer issues in practice.
