It depends. You may need it inside the system for development/test - in that
case, the ribbon connector is robust and works fine. Saving the cost of the
connector makes sense in higher production volumes.

Sound like the Tag-Connect stuff - but these only come in 6-14 pin versions
IIRC. I have not used them myself, but they look useful, and use little PCB
space.
