The biggest factor for my enjoyment, is how natural/real the performance is.
I don't like when it feels cold and artificial, no matter the perspective, no matter the actors... That's why before VR, I didn't watch many professional vids, I always went to amateur/homemade videos on the hub and other sites that were recorded by real couples and that showed real passion...
Thing with POV is it limits this, as in order to record POV, the male actor has to lay like a mannequin, not interacting much, there is always something separating them in the middle.
So, in Non-Pov, the actors have a chance to display real passion and have fun, which is what i look for... But it's not a guarantee, there's lot of terrible performances in NonPov.
The upgrade I look forward to with NonPov, which we are already starting to see a little bit of, is real couples having fun, videos with that "Homemade" vibe... Here's two recent examples :

and

I think NonPov is better suited for "Homemade amateur content" because it's just easier to record and doesen't get in the way of the couple, just like in the beginning of the homemade porn boom, couples just bought a camera and set it to a good enough angle and performed... And it absolutely dominated the porn scene for years to come because people value authenticity.
If I had the money to make a campaign to grow VR porn, I would go to onlyfans solo models and couples and invite them to SLR, giving them a camera for free, making it as convenient for them to record as possible, and NonPov is more conventient and easy than POV, you can even record flatscreen+VR in parallel like what cam models do...
I think there is a lot of untapped potential in VR porn because of how it is currently perceived by outsiders(simulation device). Just like VR videos used to be needleslly stuck with having to be 360 a few years ago, because of that same simulation ideal.
Thankfully we left part of that in the past, and moved on to high quality 180 degrees videos, and now 360 are much less popular. If VR video watching goes mainstream the same thing might happen with POV/NonPov, not just in porn but in general.
And in a small way I can already see it when I look at DEOVR SFW videos, the creators there already see this coming, they record 180 videos in a very similar style to regular flatscreen videos you would see on youtube.
However as all technology goes, porn is usually the spearhead, and so its VR Porn responsibility to bring in more people to try VR videos in general.
