My preference is always for wediboard type products as they can easily be tanked with the appropriate tapes / tanking compounds. Also because the tiles are backed with foam they will stay much closer temperature wise to the air in the bathroom therefore condensation is less likely to form making mould on the grout lines less of an issue, especially if there is decent extraction.
