If you're pretty sure you'll enjoy VR and you don't get massively ill in VR as a few people do then you're better off just going for index as it'll get you closer to the VR end-game with FBT and all. If you're not 100% on it and just wanna get your feet wet you could save a few bucks, get the RiftS to try things out, and if it's definitely your thing you can resell the rift and go index.
