Hi Stephanie I’m not sure you can really compare their accuracy. Thickness is easier to interpret though and is also a point measure and relatively insensitive to head size, so is frequently an easier surrogate biomarker than surface area. That said, we have done studies of surface area change

Subject: [Freesurfer] Thickness vs surface area
External Email - Use Caution
Hello,
I am performing analyses looking at brain measures for a neurodegenerative
disorder. I wanted to ask whether the accuracy for surface area is as high as
is for thickness? I would appreciate your advice or any references.
Thanks
