From MY fleet???? If I had BUY only one and do that TODAY it might be
Air2s. It splits the difference between my
Mini 2 and my
Mavic 2 Pro. The images from my
Mini 2 are good, but not as good as I need at times. It all depends on if you want/need a drone with a camera on it or a flying camera. But on second thought, my
Mavic 2 Pro checks a lot of boxes. I recently had a 10 day trip to the east coast and took my
M2P and was very happy with it. I figured out how to pack it for day trips that I didn't mind carrying it around with me. The
Air2s has some great features, lighter than the
M2P, not that big, takes great pictures and videos and has some great advanced features. What neither of the Air's or the Minis have is variable aperture. Maybe DJI's next release with be a suped-up Mavic Air style drone with an 8k camera and variable aperture?
However, if traveling internationally, it is probably important to have a sub 250 gram drone to bypass restrictions that a lot of countries have implemented. And many countries put further restrictions on foreigners.
