Both are really cool maps! though hydro hierarchy has a ton of untapped potential. If they'd only add an option for a base layer or two, something that would help put the geography into perspective; a simple denuted topo with a few place names, or a shadded relief background showing topography... then as you zoom in, more detail - down to aerial photos... oohh!!
