I think it all depends on the quality of the equipment and the user
technique. So far I have never been able to get my jointer to leave a
shiny reflective surface on the edge of a board. I see this regularly
with my TS. And yes, this is along the ripped edge.

If you are unable to get your jointer to improve the edge and the edge is as
Leon describes, why bother. However, my point is, when the situation, wood
condition and other factors leave the edge unsutiable after ripping, a
jointer will solve the problem.
