As a reader: I prefer the look of traditional, but for an ongoing comic it generally means slower updates, so unless it is an already finished comic, I may prefer digital. For illustrations, I largely prefer traditional.
As an artist: I theoretically prefer traditional. Practically I switched to 80% digital after I almost missed my transatlantic flight because my pastels got a security officer really alarmed. I mostly draw while I'm traveling and I can't take the chance anymore. (Actually, this year I'm going to be try to bring half of each my pastel sticks abroad and let them there. But I'll put them in checked luggage. They'll likely arrive as a cloud of dust but well... I'll try...)
