For advantages, electronic fund transfers (EFT) are speedier, more secure, and less expensive (except for international wire transfers) to process than using paper checks and making deposits of funds in person at a bank.  For disadvantages, international wire transfers (a form of EFT) can be expensive to send and receive, with fees from the originating and receiving banks, possibly intermediary bank fees, and miscellaneous fees like investigation fees if the wire transfer is lost. And once sent, funds from an erroneous or fraudster-requested wire transfer can’t be recovered because wire transfers are final.
