ok i didnt do either, but from what i've read here i why i would choose the cardstock program fans:
~rafia fans take a lot of packing space
~they take time to put together (ribbon, etc)
~they would cost more
paper fans, you print, cut, and stick a brad thingy through the corner and you're done!
plus the cost of cardstock is much less expensive, and they will pack much lighter and take up less space.
