For me the subject is easy to discuss, if I like the visual impact personally it matters not whether it be photo or a painting. I'd say my understanding and appreciation lends more to the photo world as I've done a lot of landscape photography over the years. However, my weakness of never having studied or made any attempts at artful landscape painting does not leave me lacking for a real appreciation for something I like.
Both are a good art and can be absorbed as pleasure or business as one might see fit.
