Dependent worked and received social security benefits.

My dependent son worked for the a small portion of 2019 and had taxes taken out of his income at a single/zero rate. He also received social security benefits. 

 

My question is would it be better for me to claim him as a dependent on my tax return or have him file his own return for a refund of the taxes that he paid in? The amount of SS was between $13,000 & $14,000 and his earned income was under $3000.
