Sway can result from weak springs, weak shocks, overloaded tires, and frame flexing. The anti-sway bar helps with the frame flexing. Supersprings help with the weak springs. I had minimal sway with my new 2011 GM truck and reduced it even further with new tires that had an extra 650 lb per tire of load capacity so I have less sidewall flexing with the camper load.
I believe in beefing up the stock components but not changing the way they work as with air bags or Sumosprings except as a very last resort. With a new Ford truck I would definitely add as big an anti-sway bar at the rear as I could find. I would not bother with the current Ram or GM trucks that have frames that better resist torsional loading.
Supersprings took me all of an hour to install on my truck. I like something that I can do once and then forget about it, unlike air bags or Sumosprings.
Sway bars are mainly for spring flex, they keep the axle in a level plane. The entire design is to keep the springs level, as even soft frames are stiffer than springs so the springs flex first.
They might help with a little frame flex, but mainly spring.
The reason 3rd gen Dodges dropped the sway bar is the leaf springs are wider and longer, which reduces the need for sway bars. I can tell you from experience that they are still very beneficial thou.
I find it interesting that you don't want to effect the way an OEM suspension works, yet you installed super springs. Super springs change the way the OEM spring works, and induces a non-OEM pivot point. Of all the methods you listed, IMO, super springs are going to effect the OEM components the most.
