I'm very susceptible to dizziness from ocular lab. I've tried (I believe) every Oculus product that's been publicly released. The Quest essentially eliminated dizziness entirely from me (although I've heard there are some games that still struggle, a roller coaster simulation has come up a few times when talking to people who've tried more). My uncle, who is not a gamer and is in his 70s, is seriously considering buying one as he has a friend who got one as a gift, tried it, and loved it.

Anecdotally, it seems like the Quest beautifully handles experiences designed for VR, and has a bit less success with improving media designed for traditional consumption (watching movies, which seems like it could be a phenomenal experience, still just makes me want to watch on a TV).
