The LE backglass blows the Pro translite away in person, in my opinion. I've seen them both next to each other, zero contest to me. And the cabinet art looks way better than the Pro, because that dragon flame art is great. Hand drawn > stiff PR collages every time!
I think though that the LE art doesn't photograph well. It looks like overtouched PR photos on the computer screen. Lit, in person, it's way nicer, has a real painterly feel, almost a colored pencil softness that just doesn't photograph well.
Plus Stern was only showing 3D renders, and there was some uncanny valley aspect to those that didn't present any of the art in the best light. Everything looks better in person on this game compared to the release photos, not how I would have chosen to reveal the game. I'm sure it was a time pressure thing, but just not a great first impression.
I guess my point is see it in person if you can. And make a decision after that. I'm not sure this is the game for me, but if I were to ever own one, it definitely wouldn't be a Pro.
