The good side of having your name on the account is that you can avoid probate if you are his only heir. You can also get around the problems of banks that are not comfortable with POAs. You and your dad should decide which is the best way to go. Personally, we have my name on my mother's bank accounts so I can do her banking. She assigned the POA to my brother -- no good reason except that she thinks legal things are in the male domain.
