Hi Anis,

ZBrush is focused on modifying an object by painting and brush-stroke like operations. It's sort of like you paint directly on an object and the spots that you paint on form valleys or ridges in the object.

Modo and Silo I believe have added some of that in as well, but their main focus is in a different area which is sub-d modeling.

Sub-d modeling is where you have a polygon mesh object where you manipulate a 3D point cage to edit the object. It's a lot more about adjusting points in 3D space.
