I'll wait to see the reviews for the Vive and Rift come in. I don't imagine they'll be massively different. I own both the DK1 and DK2, the second one was a big step up in usability in many respects but I rarely use it due to the amount of faff involved whereas the first was much more plug and play.
With both I spent the first 15 minutes wiping condensation from the lenses. The DK2 lenses scratched as soon as you took the plastic off.
