Although more time would be awesome(I had finals during the second week of WAR), I see Morzone's point about how despite being frantic, more of yourself bleeds through.
I guess I see the merits of both sides. You can take writing it a bit slower and easier, have more time to come up with a good, well thought out idea, polish it up and smooth out the rough edges, really make it shine. But you might get too caught up in the editing, or get too worried about its' quality or quantity if you let it sit for too long.
