I have definitely seen differences in hardiness of fig trees. Mostly between the so called 'hardy' varieties and those that typically are not considered hardy. One year I left a couple of my container figs outside too long before bringing them in. They suffered through one night down to ~6F before I remembered to haul them into the basement. I had a Chicago Hardy and a Peter's Honey. Both trees were nearly identical in size/age, in identical containers, and were sitting right next to each other. The Chicago Hardy had only around 25% dieback, whereas all but the bottom 3 inches on the main trunk was killed on the Peter's Honey.
Having said that, I haven't really noticed any major differences yet between the 'hardy' varieties. As with most borderline hardy plants, I would assume the microclimate, soil type, tree health, etc... of these trees plays a significant role in their observed 'hardiness'.
