Dennis although both my VDB & PN are in Pots my leaves are reversed PN has small leaves while vdb has big leaves. Both are from EL and both in their second season, The PN is a ridiculously slow grower more spreading while the vdb grew like a weed and upright. Neither one grew any figs in their first season.
Also have a vdb from Adriano that is in its 3rd season now and it too is a vigorous grower.
Hopefully in the next 2 season's they will ripen figs so I can compare, but right now I would be leaning towards similar but not exactly the same.
Oh another thing I remembered is that the PN need more frequent waterings compared to vdb, I litteraly had to water it in the morning and when I got home from work leaves would be drooping already and have to water again and both were in 3G pots.
