What's so bad about the SOD? I think it is a legitimate strategy. You need to combine defensive and offensive units to make a SOD effective, not just mindlessly grouping stacks of cavalry or catapults together. Also, a SOD is not invincible and can be defeated by using the right units or by attrition.
1 unit per hex, on the other hand, works on a zoomed-in tactical map like in the Total War series. It does not make sense to use it on Civ's strategic world map, where it is possible to flood the whole world with single units in every tile.
