I think every answer above (and prolly those below too) will be on point.
My feelings, having owned several of both:
Woodvils are extremely beautiful and feel like nothing else in hand. Just amazing to hold.
Grands are extremely beautiful and feel like nothing else in hand.
Woodvils, being that they are made of wood, can absorb oils and contaminants from your hands, juice that spills in the mod and cannot be washed. There are Woodvils with finishes that can prevent some of the above, but I can smell / taste those coatings in the vape. In my opinion, anything that goes in ones hand needs to be washable. Not wiped, washed - like in a sink.
Additionally if it holds juice, like a bottom feeder does, that further emphasizes the need to be able to wash it. Not only for sanitary reasons, but they can absorb and hold flavors.
I also believe that a clumsy dumb ayuss like me needs a mod with a connector that is in a material that cannot be cracked or lose grip. I run mostly big top heave attys and would worry about my unscrewing and rough handling of the attys resulting in connector looseness over time.
That is why I own only grands and I am damn happy with grands. Don't see myself ever having any other type of mod. Yes, I am allured by the resin because I believe it'll have the same qualities of a grand when it comes to washability. But, for now, I have come to realize that it is not only the obvious sturdiness of a grand that appeals to me, it's the ability to keep them damn near sterile that I love.
I'm kinda a freak though so if your a normal person, please disregard my post entirely.
