Id have to politely disagree with Cickic on this one. While I completely agree in terms of price the Quest has the market there, but... it's a mere 300 smackeroos for a reason. The guts are simply cheaper. It's like the dell Inspiron of Vr. The most noticeable part is the resolution, it's much lower than the pricier Vive sets.
Personally I have the marketed Steam VR set, which is just a branded Vive. I like the way it fits my face better than the Quest 2 (which my nephew has). To Cickic's point, it does require cables unlike the Quest. But I have them mounted to the ceiling on pulleys, so there is no interference.
As far as immersion, as my wife will attest, if the headset is on, don't bother - I'm in another world entirely.
I don't feel quite as immersed with the Quest. Mind you I have little experience with it, but going there from the Vive set was like going from a modern day computer to a Windows XP rig for me
