Agree that disk brakes take a little getting used to. In my experience there are two issues: The first problem is that all disc brake actuators have some delay while they build pressure. Secondly, I have found that the braking response isn’t linear. As said above, they work great (for me) on hard breaking or high speed braking. It’s the light, slow, braking that drove me crazy. Depending on the controller and/or actuator a light push on the brake petal may not send out enough voltage to even start up the actuator--thus no trailer braking. While Hydrastar is supposed to be one of the quickest, my biggest concern was a low startup voltage. I found with BrakeRite (now owned by Dexter) to have good, low, startup voltage. Not sure what MORRyde is currently using for an actuator—they used to use BrakeRite. One solution if using a 2015 or later Ford is to set up the brake “Aggressiveness” to Med or High. Since my older Ford doesn’t offer this setting, the only other option that I found was to install a Prodigy P3 set to Boost level B3. At that boost, a light touch on the petal gets the BrakeRite pumping with slight slowing. Once pumping it is very responsive to more aggressive deceleration. As with any controller it is important to set gain at a point where the wheels do not lock up. The B3 setting will show you right quick if you have too much gain.

Any of these guys ever thought of using an accumulator to store pressure? I guarantee that an accumulator valve will operate a whole lot faster than starting up a pump. H3ll, they're putting electric boost motors on turbos to reduce lag to near-zero. An accumulator should be child's play.
