MPB is more suited to bandgap calculations in general (with a few  
exceptions, like metallic structures).

MPB can import any shape in a variety of ways.  It can import the  
dielectric function from an arbitrary HDF5 file (see the epsilon-file  
feature).  You can also specify your own dielectric function by  
writing an arbitrary function in Scheme (see the material-function  
type).
