Archival qualities Should be similar between palladium and platinum since the two metals are equally noble. It really depends on your toner, and how much of the silver metal you replaced in toning with the more noble metal.
Consider also gold toning for vandyke as gold is even more noble than palladium and platinum, and the bluish/black image gold toning is highly distinctive.

Thanks for the input Sandy. From all the hype about platinum prints, I would have thought that it would be the more noble of the three. That's another reason to revisit the chemistry textbooks I have in the storage locker. Although this print doesn't show it as much, I have settled on palladium toner for this subject which I think complements it better that platinum or gold would.
Mostly due to the blank sky, I'm not satisfied with this negative and meant to re-shoot it on my last trip to Bodie. However I arrived tad too late as this is a morning shot when the sun rises above the ridge-line to the east where the mines are located providing frontal light on the saloon and barbershop. On the day that I shot this negative a 60+mph wind gust came unexpectedly roaring up Main street and I foolishly grabbed for the rolling case's foam insert instead of for the camera and the the wind knocked over the camera damaging the front rise which I had to have repaired by Toyo (Mamiya America).

My idea is to choose the toner according to the image and what I am attempting to depict. For example, for the image Wildcat Fall in the Kallitype thread I chose to tone with gold because I wanted a dark tonality with no browns and that's what I got. Originally I planned to tone Cathedral Rocks with gold but I underexposed the print and it came out too light and red. Thinking that the sensitizer had aged (I mixed it at the end of last year and didn't keep it refrigerated which is supposed to prolong its working life up to a year) I planned to reprint it after I had made a new batch but ended-up reprinting it on the spur of the moment with the old sensitizer - after all Cathedral Rock and Merced above was printed just a few days earlier and it (printed from a FP4+ negative) came out a tad too dark and I will have to reprint it. The former was printed off an Acros negative and needed more exposure. I normally print alternatives from Ilford Delta 100 and need to pay strict attention to the various data sheets when not printing from Delta.

For the past couple of years I have been matting my prints on 4-ply museum board complete with cut window and storing them in ClearFile sleeve protectors in print racks where I occasionally pick one out to examine. Here's one picked at random a couple of days ago that I haven’t looked at in a while:
According to my field notes the Delta 100 negative was shot on 30 October 2015 with a 480mm Apo-Ronar at f45-⅓ for 1/15th second and printed shortly thereafter as a palladium-toned VDB on Bergger Cot-320 paper.
