ACSM clinical exercise specialist VS NASM crrective exercise specialist

hi, I`m a Physio *** fitness professional. looking for a valid certification in both clinical and fitness training. can any one suggest me which one of the following certification is of greater value.


ACSM Certfied clinical exercise specialist
NASM Certified Corrective exercise specialist

Being an exercise professional; ACSM Certified is certainly more prestigious, and is also harder to attain.
