For folks with experience using a 7.3 exhaust brake, brakes for this engine must use very low backpressure to keep the lifter seated. This low pressure means low braking power, and isn't a good example of modern exhaust brakes.

That was not my experience at all. I installed a US Gear Decelerator on my '95 F350 and was very happy with it's performance. The type of EB I used included a waste gate that prevented over-pressurizing the exhaust system. The braking performance was good enough that I rarely had to use the service brakes on the truck while descending a steep grade. I also liked it better than the Tow-Haul mode on my current truck. It was much more controllable, being either ON or OFF with the slightest movement of the throttle. The braking force I always felt was very good.
Some things I did in conjunction with installing the EB were to replace the turbo pedestal with one that had the exhaust BP actuator removed and welded over removing a source of oil leaks, and gutted the exhaust BPV housing of the butterfly which improved the exhaust flow.
I used it all the time, and never had a problem with it sticking closed.
