This question is almost like someone asking, "racing coupe or dune buggy for a road track race?"
Dune Buggy (VR) is for a different application. Namely...VR and the unique experiences VR provides.
I disagree. VR is amazing for watching movies, if you don't mind watching them by yourself. I think they have a social movie theater now where you can watch it with other people via avatars, which is kind of weird but whatever. I believe they let you voice chat too, so you can pause it & talk if you want. Anyway...stuff like the Netflix VR app has a "void" mode where the screen follows you in pitch darkness & is adjustable in size, so you can blow it up as big (or as small) as you want while laying down in bed or reclining in an easy chair. It's cool to have a jumbo screen available too, especially if you don't have a big HDTV at home. It's not perfect though; I see 3 issues with movies in VR:
1. Right now the screen quality just isn't there yet. In a few years, it will be...but by then, OLED TV's will be a lot cheaper too.
2. It's socially limiting IRL, because you put on a headset & cut yourself off from your surroundings. No one is going to buy VR goggles for everyone in their family so that they can all sit on the couch for movie night. Yeah, you can do avatar-based social movies, but it's not like chilling with your SO/family/friends for movie nights
3. Wearing a headset is akin to wearing 3D Glasses, i.e. nobody wants to have to put something on just to loaf & watch a movie.
However, it holds promise. I'll catch a show sometimes while I'm on my stationary exercise bike because I can pop the goggles & headphones on & not wake anyone up when I'm working out, so that's nice. It'd be great if you take long bus rides or fly on airplanes a lot. If they can get the quality up to Retina at some point & you're a solitary person, you won't need to buy an HDTV or even a computer monitor because you'll be able to do everything on the headset:

So, it holds promise...when the quality gets there...and in specific circumstances. Eventually they'll get more comfortable, lighter in weight, better in screen quality, with more inputs for stuff. Playing Xbox or Playstation on one will be pretty huge because why buy a 70" television when you can play on a virtual IMAX screen?
