Who is the most signifigant jedi in star wars?

My favorite character in all of star wars is Qui Gon Jinn. There are things i hate about the prequels but there are more redeemable qualities to them than there are flaws. Darth maul, the fight choreography, mythology of the sith e.t.c...oh and Qui Gonn Jinn just to name a few.
So when i think of the entire star wars canon and all of the jedi that have come and gone, who among them is the most signifigant? Theres Anakin Skywalker, yoda, luke, obi wan, mace windu e.t.c. My pick for the most signifigant jedi in star wars is Qui Gonn for one simple and awesome reason. He returns from the netherworld of the force and teaches yoda and obi wan how to achieve life after death. This ability ripples out into the story and is at the root of all the signifigant moments in star wars.
Without this gift how would obi wan have been able to tell luke to head to dagoba to train with yoda? Luke probably would have missed his shot to destroy the death star because obi wan wouldnt have been able to commune with him.
Without yodas training vader would have succeeded in either killing luke or turning him to the dark side because he would have been to weak and more susceptible to temptation.
Qui Gonn even discovers Anakin, the chosen one who eventually destroys the sith, sidious and the part of him that was vader.
I am sure 99% of you will disagree but i would like to read others opinions on this subject. My pick for the most signifigant jedi is Qui Gonn Jinn.
