Seems like you got in after your issues. Glad to see you here.
The gimbals themselves are pretty much exactly the same. We have been telling people that if you are already the owner of a GoPro, the Phantom 2 route is probably the way to go. It gives you a much more modular solution so in the case of an eventual crash (you will crash it) it is easier/cheaper to fix stuff. Break the GoPro? Get a new GoPro. Break the gimbal? Get a new gimbal. With the Vision+, if you crash it, you currently have to replace the entire gimbal/camera assembly. It costs around $700...
That being said, the big upside of the Vision+ is the ease and price of getting an FPV (First Person Vision) setup up and going. Getting a GoPro-based FPV setup together will cost $300-500 more than the Vision+.
For our mapping applications, the Phantom 2 system is much more flexible, but with DJI's new software, they have introduced ground station capabilities to the Vision+.
I hope that helps.
