roof dilemma

So john and I have been going back and forth over the roof. When the project began, we were going metal roof all the way. Then when we got into budget, we nixed it to spend that additional cost elsewhere. After seeing some pretty awesome houses with it on, it is back on the table. We go back and forth about it. My thought beyond that its gorgeous, is that since we are in such a wooded lot, would it help the leaves/sticks to slide right on off instead of stick right on the shingles and collect (which is what the current shingled room looks like-covered in leaves/pine straw/sticks). Also I think it lasts longer and is more durable. We are still going back and forth though...Do people other than us even notice roofs? Is the money more well spent on the interior? Any thoughts? Sadly, this decision has to be made sooner than later...
