RE: Which is harder to hunt?
Not being an expert on either, I say big woods bucks. I've hunted both terrrains before and the nice thing about agricultural is normally, at least in Northern Mo, there are fingers of woods scattered about. Well, the deer are pretty darn easy to find. Set up in a finger and wait them out. They'll be by sometime, guaranteed.
Big woods bucks are challenging because they could be anywhere, at anytime. Yeah, there are funnels they will use, but they come from every direction you could think of and some you didn't.
