For comms it's better since raptorq can generate a large number of symbols. One use would be a TCP replacement. If a file can be transmitted in 100 TCP packets, and there's 10% loss on the link, then the client needs to retry the lost packets in order. With raptorq, the client needs to receive 102 packets (I believe). And this can be any combination of original 100 packets and the large number of potential recovery packets.
