I had a P4P+ and a P4P before going to the Mavic 2 Pro. I can't say the P4P has any advantage in sturdiness. The glaring benefits are, beyond the obvious compact size when folded, are quietness, avoidance sensors, added Intelligent Flight Modes, Ocusync, and flight characteristics. I list the Intelligent Flight modes because, from a photographer's perspective, most video is taken in simple "takes" or clips. You can let your modes do the drone flying work while you focus on VLOS activity around you and on what images/clips your want.I have now. Still Not 100%.
Like that Mavic has additional sensors and Ocusync.
Like the sturdiness of Phantom.
I have a P4p Osbidian. Love it Buy was thinking to trade.??
