I really think that gear VR is the best and most cost effective experience right now. The app store is great, there are a lot of options. An important thing is that it doesn't take itself too seriously. It's meant to be enjoyed 30 minutes at a time and that's the perfect duration for enjoying VR right now. You don't feel dizzy and you don't feel disoriented. The cost is also minimal. The headset is literally $100 or free with your phone. Apps are a bit expensive, but nowhere close to the PC based systems. Daydream is a low effort also ran. It lacks good hardware, the quality is noticably worse than gear VR and supported phones are rare to find. Now that the galaxy S8 and note 8 are slated to support daydream, it will finally have decent hardware support. Let's see if Google does something interesting, but I'm not holding my breath.
