I wonder how much the complete and utter darkness of the deep see would psychologically deter/impact the decision for underwater cities?
Also while Mars does get crazy cold -225'F it can also get up to a nice 70'F at noon. The deep ocean is 0-3'F with not much fluctuation. Of course we could engineer some water cycling around the cities to bring cold up and warm down.
The other psychological choice to make is, "Would you prefer to live in a dwelling surrounded by almost no atmospheric pressure, or intensely high atmospheric pressure?"
