as improvements are made to the freesurfer algorithms, there will be differences in results between versions (and between platforms and OSs). so you should be ok with choosing v4.5 for your results.
do not mix results from different versions though!

Hi,
We are concerned about differences of cortical thickness when we process the
same scans in freesurfer 4.5 and 3.02. We have attached an excel spreadsheet
of the differences in thickness between 4.5 and 3.02 using the mean
thickness of parcellations of both versions in both hemispheres. The
difference in the paracellations vary from 3-11% between the versions.
Are these findings reliable and explainable in choosing freesurfer 4.5 as
our final version.
Any comment are greatly appreciated,
Thanks!
