Square grids are more intuitive: they map to our standard cardinal and ordinal directions. As long as you treat the ordinal neighbours (the corners) as being sqrt(2) away from the center (as oppposed to 1 away from the center like the cardinal neighbours, or all of the hexagonal neighbours) then you don't get spatial distortions.
