Funny, that seems to be a debate among some people.
a lot of people thing that Organic modeling is easier then hard surface, because with Hard surface you are recreating something that has to be perfect in structure,planar faces, ect. you have to figure out how to add tight edges without getting weird creasing through the rest of your model.

and on the other hand some people thing that hard surface is easier then organic. ...for much the same reasons.

it is an issue i believe that depends on the person, and the skill sets they chose to develop at an early stage in their learning.
