I see mileage varies per person, so by all means feel free to decide for yourselves.
I specifically wanted something for headlook, and no VR, no hat, helmet or headset attachment (People who know my medical history know why. ). I almost thought about adding a tracker thumbstick to my hotas especially for headlook. For me the Tobii 4c is the best solution for my wants. It doesn't jitter when i tilt my head (it sometimes does that), but follow what i'm actually looking at. To me, it adds to the immersion. To me, is is a great build, well executed, just works out of the box.
