That's interesting, I disagree. It'd be cool to actually pair the two somehow. I like to alternate map perspectives as I gm so the players have more terrain challenges and get to use more non-combat skills. Also more precarious combat.
If each room is assigned a depth, a generally linear dungeon could be easily laid out in both perspectives.
If rooms were color coded or something, this could maybe allow sideviews which account for less linear dungeons
