I'd honestly be happy with either. That being said, I do have a Vault, and I like the ability to be able to remove the lower playfield window on the Vault, but with that comes the need to make sure that window is level, and on a rare occasion, the seam between the window and playfield may influence the direction of the ball (that hardly ever happens though). On the original Luci I do like seeing Phil Rudd instead of a mysteriously darkened and shadowy drummer on my Vault, so maybe Phil's representation makes the original Luci release more valued with collectors. That would be understandable, as it is AC/DC after all.
