I would recommend IOS. Much more user friendly. I have the Tripltek tablet and it’s a PITA TO Upgrade. Only thing going for it is the bright screen.
Also I have both Litchi and Maven on my iPads.
The great Debate Hmmm...I will say IOS is friendlier for dji Drones I don't think its really any Better. I would say Apple is better for novice Drone users. I.M.O.
