I will go with others and say conduit. None of us know what the future will hold. You can be installing something that might be obsolete by the time it is to be used, so what use will it be?

I remember (and I am sure most here) some guy that wanted to work on the perfect structured cable and how his idea was to have all homes bringing that structured cable to all locations as future proofing. None of what was included in that cable would be useful today.
