The Colonist probably offers the most room for roleplaying - there's not a lot dealing with the slums of Earth, and as Shepard is a military wo/man no matter what, the Spacer origin doesn't really add much. In contrast, you run into lots of batarians that offer room to roleplay your Colonist in various ways.
