I'd rather hunt an edge if at all possible because it's easy to get into and out of your stand without waking up the entire woods and spreading your scent around as well.
Hunting in the heavy woods is like hunting in the deers living room. They know exactly where you are nine times out of ten, or they will know soon enough.
I'm my experience trying to go set up in heavy woods just drives the buck/bucks out. It's easier to get in and out quietly on the edge of a field.
I'd rather let them feel safe in heavy cover and wait to catch them in the open when they need to feed or chasing tail.
