I have the VP-X sport in my RV-9A. I would install another because I like the utility it brings to the electronics. I have auto wig-wagging lights. Flap and trim control and the ability to see just how much current everything is pulling.
HOWEVER, if the VP-X goes on the fritz, you are stuck. Yes, this happened to me during my Phase 1 period and the unit came out and went back to Vertical Power for repair twice (their problem, not mine). After the second time, I ended up getting a replacement unit under warranty, and it has been rock solid for the last 4 years of flying.
If I were building something like a -12 or -14 where the electrical systems are all laid out and part of the built harnesses, I wouldn't change that and put in a VP-X. There are benefits to having it, but again, there are some downsides that would need to be considered. The fuse panels that Van's have in the -12 and -14 are just fine.
