My understanding is that DJI deliberately switched to 5.8 for control - not because 5.8 was superior, but because 5.8 was inferior range-wise. This might seem backwards because DJI was already using 2.4 for control on the original Phantom (which didn't include built in FPV), so intuitively, one would think they'd use 5.8 for FPV. But by switching control to 5.8, this freed the 2.4 band which allowed them to use it for something they had never done before - provide FPV AND telemetery built in and ready to go in a single quadcopter. This makes sense when you think about it because the FPV and telemetery wifi signals do an incredible amount of work both coming and going whereas the control signal is just a simple one way signal. It's ironic because the Phantom 2 Vision released in the fall of 2013 had even less range than the original Phantom. But DJI deemed it necessary to switch to 5.8 even if it meant losing range due to the complexity of the FPV and telemetry wifi signal. And so the P2V was born.
When the straight P2 came out (ironically after the P2V was released), it followed in the footsteps of the original Phantom in that it used 2.4 for control.
Then, after the P2V+ was out, the P3A was released with Lightbridge, which enabled DJI to use 2.4 for everything.
And then, after the P3A and P3P was released, out came the P3S. But again, like the straight P2, it followed in the footsteps of its ugly stepsister, the P2V and P2V+, rather than its better looking and smarter brothers, the P3A/P.
The P3S is really just an advanced version of the P2V.
