For me, headlook mode doesn't work in Elite when a HMD is used. I tried using an EDTracker with the Pimax to overcome its terrible tracking problems, but headlook mode becomes non-functional even if you disable the Pimax's built-in gyro sensor.
Compared to the Vive (which I also have), the Pimax's resolution is definteily welcome, and you do get used to the 60Hz, but the black levels are not as good (it's not using an OLED panel), and the current tracking problems make it a pain to use. If it had better tracking, I'd recommend it due to its price.
Also remember that it uses HDMI 1.4, so cannot operate over 30Hz if running at resolutions higher than 2560X1440. That said, 2560X1440 seems pretty damn good.
With all of this in mind, one can either await the noloVR tracker and hope it integerates nicely with the Pimax, or one can wait for the release of the FOVE. Given the total package, the FOVE is what I'd call the first true second-gen VR headset.
LG are also coming up with second gen hmd real soon
