So, our autistic 7 year old (mostly non-verbal) rarely plays with any particular thing for a long time, but the teachers at school put him in a VR set and he watched water for 45+ minutes.

We're thinking of getting one for his birthday. He hardly wants anything, so it'd be nice to do something special. Any recommendations? Thinking a meta quest 2?

I don't think he generally understands or cares about the gaming aspects of things, so we're more interested in open worlds, especially aquatic ones, that he could get immersed in.
Also not concerned about movement because the little God runs around the world 24 hours a day. He had a six pack at age five. He can do situps from a hanging position.
@ZachWeinersmith I have a Quest 2 and if I was doing it over again today I’d drop the additional money for the 3. I don’t think it does a single thing VR-wise that I care about but the pass through to see the outside world is supposedly a lot better.

@donw @ZachWeinersmith i owned a q2 and now a q3, assuming money is not a concern i'd go for the q3, imaqe qualitys so much better, and a bit better on the neck, too (you might want to look into a better headstrap if long sessions are common).

of course the apple vision pro has an even better display, but it's quite front -heavy, reportedly (and way too expensive imho).
