Didn't you ask this question yesterday? Please patiently wait for a response.
My thought would be--Non-linear registrations have more degrees of freedom, and happen according to more parameters; therefore the result is probably more exact across subjects (with regards to the images all being in the same standardized space). This is not necessarily so, however. Let someone more experienced reply...
