Make sure you get one thats PC capable as well as stand alone, regardless what kind you get...personally if I were to buy another now, I'd go with a Vive, the tracking is way better and I FB keeps killing headset support on a whim as well as changing its terms over Meta.
Which is going to turn out to be social garbage anyways, a sad failed attempt at a somewhat Matrix/SOA type reality. The beginning of the end, but a very sad beginning, we are years away from getting THAT concept right...it'll be another 3 headsets (they kill off) before they even get a terrible one up and running decent heh.
Vive is much more pricey, but one headset has survived 3 different Oculus versions, give or take...and you can add alot more small but great accessories like finger tracking (Iron Man), or simple tracking strips to tracking ANYTHING in VR (think ashtray, coffee mug, etc) where the Rift at least has nothing of the sort, the Quest added AR to see the background but it sucks from what i've seen.
I'd need to buy the Vive Base Station to add those things and thats what the big cost difference actually is
