I don't quite fit your request, but I do have (1) 2006 in the driveway with AHC, and (1) 2000 in the driveway with OME (medium 860).
(Prior to adding LT tires, the AHC vehicle was typically kept in #2 (the next to softest setting). After adding the LT tires #2 seemed too soft and it now stays in #3 (next to firmest)
In my case, on-road the AHC vehicle is more pleasant on road (up to a point), than the OME equipped vehicle. The OME feels a little "sporty" compared to the AHC (kind of like #4 on the AHC) the small bumps are kind of harsh, but it takes the larger bumps better. (Speed bumps, AHC is better. Speed humps the OME is better.)
Off-road the AHC is fine, but I think I prefer the OME.
It took us some time to dial in the OME kit on my son's vehicle (the lift was installed by the previous owner). We added the diff drop, aftermarket UCAs, swapped in 860s for 865s and added little weight, along with dialing back the torsion bar "lift" a bit. His vehicle went from riding and driving like crap, to a very pleasant vehicle to drive. If you pull the rear seats out and remove his recovery gear from the back, it does get a little bit of the unloaded F250/2500 type ride. Our solution was to keep the seats and recovery gear in the back unless we're hauling something.
I didn't have to switch, but am happy driving either. If my AHC goes out, or my load is consistently causing the vehicle to drop to "low", I'll swap in the OEM non-AHC parts that I have in the garage, or an OME kit, but I'm not ripping out a perfectly good AHC system for an OME kit.
