Also I'd consider Microsoft too. Its Hololens is the best AR device available currently. Although it focuses on enterprise and still clunky to use, the company has quite good track record recently and I have faith in them.

If just Apple vs. Facebook, I'd vote for Apple. Apple would rather kill a product than release anything mediocre or exprimental.

I hope and expect that you're right: a) no-one needs any more Facebook in their lives, and b) Apple will probably start off decently and then can iterate.
