Recumbents vary widely in their configuration and character. You've focused in on suspended short wheelbase bikes. I would strongly advise you to find a dealer that sells a wide variety of bikes and check them out. Try a few, then take long test rides on your finalists. Plan it as an all-day affair.
While the bikes you've identified are well regarded for touring, you should also try unsprung and long wheelbase bikes. LWB is highly regarded for touring. Make sure the bikes you try have good handling at both high and low speeds, while loaded. Make sure they can carry the load you intend to take, and that loading it up does not compromise handling.
Regarding suspension, I/we have toured with an unsuspended V-Rex, a sprung Vision R42 and a Vision R82 tandem with sprung stoker seat (since removed). Both of us found suspension to be of little value, and a fair bit of added weight to drag up mountains. My wife has disk problems in her back, and has not had an issue with shocks. Unless you have back issues where shock of hitting a bad bump could "ruin your day", I wouldn't bother with suspension. Long wheelbase will buy most of the comfort you get with suspension. LWBs also handle well on fast descents. (I use SWB because it's a multipurpose bike and has to fit in my car for commuting to work.)
Good luck with the search.
