For me, I purchased the 1000lb bars and on such roads, the porpoising was a PITA. So I installed air bags which work great. But had I purchased the 1200lb bars, I may not have needed to do this.

Back to your original question, pro-active is nearly always better than reactive. A sway-control bar on a travel trailer will help to reduce or eliminate sway. Without it, once it occurs, the “reactive” control may take over. I’d rather not have to have a component that reacts, if it can be eliminated or reduced prior to the occurrence.Tom and Janice (also known as Richter on the “Other” forum)

I believe everyone agrees. The electronic sway control is set to a high gain and will control once sway is present and excessive. As you pointed out its best to have a proper hitch to not allow one to get there in the first place. I like redundancy so using both mechanical and electrical devices will ensure the trailer will not get into a dangerous situation.

Just so everyone understands, the Ford built in sway system controls sway by individually control the rear truck brakes. When the built in gyros "see" trailer sway, the system will apply either rear brake to try to get it under control. A Ford engineer, several trailer techs and a number of individuals who have the system on their trucks told me to turn off the built in sway system IF you are using a hitch with sway control. The issue seems to be the truck and the hitch sway controller would fight each other. Having been through that, I found once sway would get going (with sway control on), the only way to get it under control was to slow down. When I shut down the truck controller, I've found changing speed (either slightly speed up or slow down) to get things back under control.
The other thing is to purchase a good WD hitch. We were able to rid of virtually all sway issues by 1) turning off the truck sway control and 2) use a Blue Ox Sway Pro with 1000 lb spring bars. Our trailer is a 2020 Imagine 2600 RD. The design of the Blue Ox has sway control built in using the spring bars. Definitely beats the Equalizer hitch we first owned.2020 F-250 Lariat 2WD SuperCrew 6.7L, Blue Ox SwayPro hitch w/ 1000lb bars

Good Information where systems or brands may vary. There are no issues with my GMC while running with my Equalizer hitch.
Here is some information on Yaw sensors. Also in stability programs are steering wheel angle sensors which can provide feedback on the intended action of the driver.

I was told by my Ford dealer to deactivate the Ford electronic sway control if I am using a mechanical sway control. I was told the 2 will "argue" with each other and can exaggerate any sway experienced. I have my off and find the truck handles better.2019 Imagine 2670MK

My Blue Ox factory rep told me that if a customer's truck has integrated sway control, they should disengage the truck sway control if they intend on using a wdh/sway control hitch (Blue Ox Sway Pro), as the two will work against each other.Scott M. Barlag, RV Product Specialist, NW Indiana
