With the Vision + you get the 3 axis gimbal and the new Transmitter. The camera/gimbal is notoriously fragile, but works fine as long as you're not crash prone.
The Vision is quite a bit cheaper, and you can add a RotorPixel gimbal for around $400. This is now a 2 axis gimbal, but they're working on a 3 axis model. The 2 axis model will be upgradeable to the 3 axis. It looks like they're still shipping the old transmitter with the Vision, but you can purchase a new one for $99.00... The camera/gimbal on this set up has proven to be pretty rugged...
