The increased attack range allows Takohs to take down Spies from farther away, even beyond their own line of sight, and their additional Craft gives them an extra edge when having to dispatch more than one Spy. Takohs' ability to hide when not moving also gives them an edge over the standard Scouts, as they cannot do so until they are upgraded to Explorers in the Medieval Age.
If the Iroquois have standard Scouts in a scenario, they will still be able to move through forests since the ability to do so is given by their nation power. Conversely, if another nation has Takohs, they won't have the ability to move through forests, which will never happen in an ordinary match since Scouts cannot be bribed.
↑There are "Pathfinder", "Pioneer", and "Ranger" entries in the game files which is supposed to modify the damage taken by the Iroquois' unique Scouts, but possibly due to naming error, these lines have no effect in-game, despite being in the correct location.
