Well with Lenovo don't know much save a standalone with fcc approval. The other one is truly not entirely new as the power glove used ultra sconics & i believe thats part of nolo as well. But the 6dof on headset & controllers decent.
Now if you want way over priced to the point it looks like PiMax is giving away the 5k/8k headsets; look at herovr. Lol
As for best deal? If Psvr still selling for $200 US makes it the best for price point. There is an awesome Reddit post detailing how amazing the psvr can be with SS jacked up & only suffers a minor drop in res (negligible) with less sde. Sure tracking is amazing on controllers but still decent with a dark/light controlled room.
But yes i would concede that for the lay man the oculus deal would be better for ease of use. I would like to see both psvr & pimax 4k with a vive puck for head tracking
