Toslink or 110 ohm aes/ebu?

My aging Museatex transport broke down and I am awaiting delivery of a CEC TL51X. I use a bidat which was recently upgraded by John Wright. Because I also have a Wadia 170, which only has a coax connection, I used a VDH Octocoupler toslink between the transport and the bidat. With the CEC I can use either the toslink or a 110 ohm aes/ebu interconnect. Any thoughts on this as to which would make the better connection with this equipment and recommendations for which brand? I know the gospel here is to try different setups and see which I prefer, but I looking for recommendations as to where to start.
