RE: What do you think is more challenging?
One year I did both at the same time but not simutaneously.
I personally asked a warden if I could have both weapons with me during the gun season. And specific to the area I was in, there was no rule against it. So... I brought both and intended to use one or the other based on the situation.
Because your question doesn't cover any variables or conditions, I'd have to say bow.
