Parent PLUS loans and Refinancing

My dad took out $25k in parent PLUS loans. I will be paying them back. I have $78k in my own federal loans too.

My dad thinks it’s better financially to refinance the parent plus loans to a private lender for a lower rate (in the 5% range) to pay off in 5 years rather than keep the federal loan lender where interest rates are in the 6-7% range.

I swear there’s more protection through federal loans, but he’s not sure and would rather I be able to pay off the parent plus loans as fast as possible (to save as much $ on interest). I will be eligible for PSLF based on my career so I’m less worried about the loans in my name.

Does it make sense for me to refinance the PLUS loans to private in order to get them paid off? Or are there actual protections that are worth having through federal??
