I own a P3, P4, and TH. I was attracted to the TH because of the all-in-one controller, safety of losing a motor, 360 camera views, and the amount of control you have over just about everything.
I only flew the TH 17 times before it flew itself into the ground. Their support is far better than DJI, but it's still a nightmare, and not what consumers should be put through for a $2-3k investment. While the controls are nice, to fly it requires a lot more practice, and many of the features are undocumented, or do not have the safeguards that DJI does.
My P3 has flown hundreds of times, and my P4 is flying right now. I think several people have said similar things: when I need to get something done, I use my DJI platforms. I think the TH is still somewhat "experimental" and they don't have the years of using us as guinea pigs like DJI has to perfect certain things.
However, I think their support, combined with how fast they seem to be learning/adding features and fixes means that we could finally in a year or so have legitimate choices as consumers.
