Yeah, KW can actually add the hydraulic height control to any of their shocks if you send them back to them and have versions to work with or without factory electronic control.
The Falcon's in my mind are a little closer to something like Fox's IQS, sort of a dumb we let you change a setting for all shocks, between two or three settings. The eAdapt goes a small step further by having a sensor that will auto hit that switch for you, but it's not doing anything intelligent.
E-Clik is more like the Raptor and TRX systems, where they are trying to build a profile of how you are driving and adapt in real time based on that. The Raptor has the famous jump mode, where it senses you leaving the round, dials the compression damping up to full stiff and also relaxes the transmission clutches all before you hit the ground to lessen the impact on you and the vehicle.
The E-Clik is trying to do that, but of course like every programmer they think their algorithms are smarter
I did chat with one guy who had swapped out his Raptor suspension controller from OEM to the E-Clik and he did agree that he thought it was much smarter about it but I have no first hand experience. In brief conversation with them it's much more individual wheel level control though, interfacing with your vehicle's sensor network to get input on what you are wanting to do, so if it sees you turning into a corner based on the steering wheel angle changing it can stiffen the shocks on the outside of the corner to reduce body roll, of if it senses you are trying to slowly roll off of a rock based on your brake pressure and feels the suspension drop away from the chassis, it will stiffen the suspension on the axle that dropped only to reduce the amount you compress the suspension on the way down, reducing the chance you compress so far you scrape something.
I'm about 90% sure I'll try it out on my truck in a few months, if I do I will report back and share my experiences. They make a universal reservoir kit that bolts onto your existing reservoir shocks, fox, icon, king, whatever, but I'm more interested in the vehicle specific kits that have greater knowledge of what you are doing while driving so it will take me a bit as I won't order them until I confirm I can emulate a Jeep's sensors from my G-Wagen to a sufficient level to work with the Jeep version of the E-Clik shocks.
