I would say yes & know. On VR as a whole yes HTC & Samsung are in competition. However pimax ultra-wide fov; it has no competition save expensive non-consumer headsets. The others are still using the basic tunnel scuba mask fov. It surprising that neither even bumped it to between 140 - 160 would have made it more direct competition.
The same its interesting Acer is sitting in the bush with their basic low end WMR headset. When as they are they the majority owner now of StarVR; it’s curious why they released such a meager product.
