Honestly for the money, the portability, ease of use and upkeep I'd go with the quest or wait until HTC , Pimax or some other company comes out with their response to the quest. I know it has less games but more games are being ported every couple months and for the price and usability I think it's almost more worth it. there are no cables and ports to screw up and trip over that cost 50 dollars or more to replace. (this is what I mean by upkeep)
As of Oct 2018, the best VR value for tethered PC gaming is going to be the Oculus Rift with touch controllers at the MSRP of $399; During launch, when Rift only came with an Xbox controller, the Vive was a much more comprehensive solution, but they're both pretty much on par now. The main trade-offs to consider now is that Rift demands more USB3 ports since it relies on external USB cameras, whereas the Vive lighthouse beacons need more space/separate plugs.
