I recently consulted as a VR programmer on a Quest 2. There is a built-in way to see your PC screens in the headset (I can't remember what it was called). I used the Oculus Link cable.

It worked and I could certainly program. But it was far from comfortable. The resolution is very noticeably worse than on my physical monitors. I don't know why OP's experience is so different. I suspect he's just willing to sacrifice crisp text for the coolness of the experience.
