I'll chime in because why not? (Late to the party, sorry - those in the know will know why, and it's got one purple leg

)
I've had a P2V since release day, and I love it. It's absolutely right
for my purposes, and it absolutely fits
my lack of electronics expertise and desire for plug-and-play use with minimal extra stuff to bring along with me (always have my phone on me).
I have bought and fitted the Rotorpixel gimbal and it's gone from a quality of video that
I was personally happy with to a quality of video that
I am personally ecstatic with (see here for some footage using the gimbal:

Now note the emphases I placed above. I do not use my aircraft for professional purposes, nor do I intend to do so. I mainly share my flight videos with friends and family over YouTube - they never see the uncompressed footage so higher quality bitrates, etc, isn't a factor there. My friends and family without fail tell me how great the footage is and enjoy seeing the world from a new perspective - they haven't seen anything like it before so have no comparators: no one turned round and said "the video's a bit shaky" - whereas loads of them have now commented on how much
smoother the gimbal footage is. Crucially none of them paid for the privilege, though!
I did a video "review" of the P2V as lots of people had asked whether they should get a Vision or P2+GoPro package and I still stand by the conclusion I drew in that: If you want to use your aircraft for professional purposes - either print-quality stills or video that you intend to sell/offer as part of a service (or think you might want to do either of those soon) then you probably shouldn't go down the P2V route. If you want casual, fun, out of the box, minimal fuss, all within your smartphone app, perfectly good for youtube sharing video and emailing/web sharing stills? P2V is a great out of the box system, and when you think what they've condensed into the package in terms of technology - the telemetry, total in-flight camera control (not just shutter, but ISO, WB, EV, etc), etc - and the fact that soon we will get autonomous waypoint flying in an upgrade for free (P2 need to buy additional hardware and own an iPad) then for users like me it's fantastic.
Only you can decide which will suit your immediate and near-future needs. It's completely irrelevant to your decision what I feel, but I am quite fond of my Vision.
Whatever you go for, have a blast with it and come and join in with whichever sub-forum here is appropriate to your final choices.
