Personally, I wanted to get into forensics at at the time, I was finishing my undergrad via CUNY (City University of NY) and I continued and got my Masters in Forensic Computing from John Jay College of Criminal Justice. They renamed the program to Digital Forensics and Cybersecurity.
It was a great program, and you learn the "under the hood" of what happens when you use forensic tools. Really helps with knowing files signatures, carving, MFT, hash sets, timestamps, etc.
That said, I also have my EnCE (EnCase Certified Examiner), CEH (Certified Ethical Hacker) and CFSR (Certified Forensic Security Responder) certifications. It does help to know and use the tools if you can do so, either via a masters program or via tool/course training. )
I think Master/Ph.D. everything has their individual importance so it totally depends on you what you want to do or achieve that course you should do.so it totally depends on your requirements.
