One of the simplest and most concise explanations of the 1/24, 2x standard/preference can be seen here:
How Shutter Speeds & Frame Rates Can Be Used to Change the Look & Feel of Your Film
I would say that for drone footage 24 fps is, as has been mentioned, just too slow and "jittery". 60 fps seems ideal but the quality just is not there yet (for 4k) so my current choice is 30 fps.
Still, I find that slowing down the shutter speed towards 2* framerate still has it's place to avoid the super-sharp look you get at say 1/1000.
This certainly depends on both the scene and the indented usage and therefore ends up as a creative choice.
In the example below, I have for the waterfall scenes, gone the other way by slowing down as much as possible (1/30 shutter at 30 framerate) to maximally blur the water and avoid a almost digital look.
(edit: go to 1:40 for waterfalls, the linking removed the time-indication)
But again, going for a super-fast shutterspeed is a valid creative choice.
