I definitely agree with you on VR Worlds. VR Worlds is a collection of REALLY nice looking tech demos. It's nice but the only thing I'll ever revisit on it is the London Heist shooting range. As simple as SuperHyperCube is it has a strong aesthetic, plays great and it has the kind of depth present in all great puzzle games. I think SuperHyperCube is worth the price but I guess that really comes down to personal tastes.
How is Batman VR? I feel like the Big PSVR releases are Rez, Batman, Rigs, BattleZone and Eve Valkyrie. I played Rez, Rigs and BattleZone with Rez being the only one I bought. Rigs and Battlezone seem cool but I see them becoming ghost towns REAL fast. Same goes for Eve Valkyrie. So that just leaves Batman in which I generally love Batman stuff but everything I've seen of the VR game looks kind of lame...
Batman VR standing with Move controllers is awesome (can't comment on sitting or using a DS4), really immersive, looks fantastic the majority of the time.
I don't know what you've seen that makes you think it looks lame, I didn't look at anything about it on the net but I did demo it at EGX and that sold it for me.
If you're a fan of the good Batman comics, cartoons, movies & games I'd say buying it is a no-brainer. If you're just a fan of the Arkham games then maybe not as it's such a different experience.
And Rigs is a lot of fun. I've seen people in this thread mention they've had a problem getting online games but everytime I've played online I got a game quick (I have only played about 8 online matches so far though, spending more time in SP).
I think the online for Rigs will be OK for a while, it's one of the most polished games available and it's such good fun.
Even if online does become a ghost town I'm confident I'll get my money's worth out of it anyway, there's enough to the SP to keep me playing & enjoying for a good while.
