One difference is the Stay-IN-Play DUO is proportional while the InvisiBrake is progressive.
"Proportional" applies toad brakes in relation to how hard the motorhome is braking. In reality they can never perfectly match but you get the idea.
"Progressive" applies an increasing amount of braking as a function of time with no regard for how the motorhome is actually braking, just that it is.
From the InvisiBrake manual:
Extended braking protection
To protect the towed vehicle’s brakes, InvisiBrake will automatically release braking pressure after an extended period (approximately 15 seconds) of continuous braking — for example, someone who constantly drives with their foot on the brakes.
The InvisiBrake requires a manual adjustment of the pressure and test drives to determine whether the braking is too little, just right, or too much.
The Stay-IN-Play DUO uses an accelerometer to adjust the braking pressure. There is an initial adjustment to assure the brakes are not coming on too early and then it's automatic from then on.
In practice, users seem to love both systems.
