I've found that the Oculus Quest is not perfectly comfortable for multiple hours of uninterrupted use while gaming, but I've not tried it for sitting at a desk coding. YMMV, I would wager that moving around while playing requires it to be tighter, and therefore makes it less comfortable.

The Quest might be the best one to test for travel though; it's relatively cheap, has fairly good resolution, and though it normally works as a standalone system, you can also tether it over USB3 to your main machine's graphics card:
