Seats on airplanes should not be abled to recline. The impact for the passenger behind you is always negative.
Just set a mild recline to all seats and lock it in. Making them adjustable is just asking for conflict.
The design of an enclosed space should be to minimise conflict. The fact that people will be entitled over either "right to recline" or "personal space" is just a point for unecessary conflict.
Keep it simple, keep it same for all.
