That's still a form of interacting.
I get what you're trying to say, but don't dismiss a PF or a similar type and caliber of collectible offhand.
I've had many PF's, though I've since sold them all to focus on 1:6 and prop replicas. Statues, though static, can have a different sort of weight, dynamism, and presence that a figure doesn't quite have. Not every PF comes out as well as they can or should, but those that are sculpted, painted, and fabricated the best are showstoppers.
Though their static nature can seem a drawback, being sculpted in a singular pose means everything is intended to work and flow toward that pose. A figure is intended to be moved and posed in different ways, so there can be a sacrifice (negligible to large) in dramatic effect to allow for that.
And yes, from experience, I would consider setting up, photographing, displaying, viewing, sharing, and enjoying a PF interactions just as much as I would posing a figure.
That said, whether this or the PF is a better purchase is purely up to the prospective buyer. If the production Kylo Ren PF comes out amazing and you like how it's posed and sculpted, great. If you want something that you can pose once in a while, we have the figure for that. Which I may consider getting since I do love Kylo. I think it's great we have multiple options available.
