freefem++ has more functionalities, but you can solve a lot of problems using 
ff3d... It depends on what do you want to do ...

ff3d does not incorporate any mesher. But there are two ways to deal with 
complex geometries in ff3d:
- use the fictitious domain methods, or
- use the standard finite element method using an existing unstructured 3d 
mesh of tetrahedra (you can build it with gmsh for instance)
