Both are good choices. Which ever one you decide to get, make sure you get insurance either from DJI or other source.
Mechanically, I have found the Mavic Pro to be my favorite of the 2. I have owned and repaired many of both, and the MP has better range, more parts availability, and has stronger landing gear than the Air. If you do break a leg on the Mavic, you can find replacements. The Air's parts availability is still sparse but will prob catch up by the end of the year.
In terms of crashworthiness, the MP wins hands down. The
MA is more fragile in a crash, more parts break, and they are more expensive and more difficult to replace. The MP is built like a tank, I have repaired them from 50' falls on to concrete and all it might need is a landing leg or arm. Conversely, the
MA would be totaled in that same situation.
