I had a phantom 3 pro 2 months ago, quickly realized it was big and bulk and made it difficult to pack around. I upgraded to a Mavic pro. Hell of a rig. fast and fun you you want to buzz around. super range, great 4k camera. Had it a month, flew it a number of times, got some great Mt Rainier sunrises. Then it got cold/wet and it sat. Realized I had much better things to spend $900+ on and sold it. Sometimes I wish I had it when I see a really killer sunrise/sunset, but usually I am already going someplace and would not have the time to stop, deploy and shoot anyway so...
I will recommend the Mavic over the phantom just for the sheer portability, it is honestly incredibly small. I had the fly more package and it all fit into a bag a little bigger around than a 1# propane camp bottle. I had mine over 1800ft away from me, completely out of my sight and down below treeline so no direct LOS and it was still solid signal. The mavic also has new props available from the platinum version that are a couple Db quieter but more importantly the pitch is lower and far less annoying.
If you have free time on your hands, enjoy any sort of photography it could be a great fit. Or if you are travelling often to places with great scenery. Just realize, they are prohibited in all national parks, to the tune of losing your drone and hefty ($1k?) fine. Many other places also prohibit them.
