I must say that I know a few people who own some examples of dogs of both breeds in the UK, though because of the care for each breed, the best are selectively bred and selectively distributed within the populous. There is some awesome old school Curto blood in the UK that is hard to attain anywhere else, as well as some impressive examples of the Boerbeol as well. IMO, it would come down to size and personal preference if both were obtainable...
