OK then, what factors would affect which one is better?

Rig geometry of course!


Now we are getting somewhere.

What rig geometery would favor a frac rig (remembering the issue of jib
head tip vortex)? Would aspect ratio be significant (again, just a
reminder, jib head tip vortex)? How about the head angle of each sail
respectively?


... This reminds me of children who are too
lazy/stupid to frame a question properly and don't really want to know
the answer but just get attention. They just keep saying "But why..."

So, even your toddlers are asking you questions that you don't know the
answer to?

All you have to do MC is supply a coherent answer to the question.
