I wonder what the goal of this poll is ? We all want better controllers, all of the above have their downsides, none work perfectly. I think this is actually a big downside for the Pimax 4k. You have the best display but since all controller options basically are horrible, there will be a group of people that doesn't even consider Pimax 4k a serious option.
I think everybody wants laser 6DOF that actually works, no drift, 360 degrees.
