In a separate thread, a discussion has evolved to discussing the difference

I believe that if all of the equipment is setup properly, all blades are
quality ones, sharp and the procedures are sound, a jointer will still
render a better quality surface than a tablesaw time and time again.

Thoughts?

Intuitively, it feels like the jointer should win even in the
best conditions for the tablesaw. Each cut of the jointer is
done by one blade which is a straight line moving to form a
cylinder. You now concatenate very close cylinder surfaces,
so the finish should be very smooth.

With the tablesaw, you achieve the cut plane surface by
concatenating parallel circular lines -- if you move the
wood too fast, it would tend to form grooves (you would have
a surface akin to an old vinyl record -- an LP). If you
move it slowly, it's better, but it still sounds like the
surface should be more irregular than in the other case.

I'm no expert, BTW, but this is what my intuition tells me.

depends on the tooth pattern. a saw blade made for finish cuts has big
teeth with fairly long faces. the edge of the faces is a cutting
surface which overlaps the cutting surface of the previous tooth.

it's not just cutting at the tips.....
