If you guys are considering Vive vs Oculus here is my personal experience testing them out. the Vive is light but the oculus feels noticeably lighter (thought you wouldnt be able to tell that the vive is a heavy thing if you only have it.. it does feel light..just that oculus beats it in comfort)
Vive is super fun, walking around and doing crazy stuff feels amazingly real... oculus is designed for a seated experience, and while it lacks that extra realism, its much more suited for gamers who like long sessions (you WILL get exhausted with the vive).
most games on both are little more than tech demos, fun to play, and you keep coming back cuz of how kickass they are (replayability is much more so with the vive) but you cant help but wish for a real game, something more fleshed out. though i have to say while games feel funner on the vive, oculus exclusive games look more polished. check out games for vive on steam and for the rift on oculus's page to help you decide.
screen is a bit clearer ( a bit) on the oculus but feels like it has a wider field of view on the vive. Though both feel like they could use a real resolution bump. Even though once you start playing, one minute in you would be so engrossed in how realistic it feels, your brain just fills in the gaps and you dont see any of the missing details.
My personal choice? I got the vive, cuz of the room scale, and cuz i felt betrayed by occulus and its policies and pricing (you would understand if you followed them like i did since their first days as a kickstarter) and while it is crazy fun to play, and almost just as fun watching your friends and family members get blown away when they first try it... I realize now (had it since release) that maybe Oculus would have fitted me more...
Most days I come home tired from work, and while i feel like playing, I dont feel like jumping around, dodging bullets, blocking swords with a shield while hammering on someones head with a hammer... no matter how fun it is (and it is VERY fun), i just want to get comfy, drink a cold one and play something fun and in no way physical, and the oculus library helps much more with that, but that is just me and you should figure out what fits you and your lifestyle more.
Those were my 2 cents worth, I hope it helps.
