3D-modelling vs. p(r)

I'm a newcomer to the world of sas, using the technique for studying 
biological macromolecules in solution.

Now I'm only modeling using simple geometrical 3D models, which are 
transformed to theoretical scattering intensities, incorporating the resolution 
function. The theoretical intensities are then fitted to the data to 
extract the parameters describing the model.

I wonder if anyone could comment on the advantages (if there are any) of 
using indirect transform methods to obtain the distance distribution 
function p(r), and then evaluating the 3D models to p(r) to obtain the 
model parameters.

If anyone has an opinion or a reference describing the advantages, 
I'd be glad to hear!

Thanks a lot!
