Suggested by iKnowledge Ahsoka is definitely a very well known character and she developed into one of the stronger Star Wars fighters. Her dual blade style was hard to deal with. Additionally her Force powers are at a high level. Krayt has both of those abilities as well though and is not only a capable fighter but a very powerful one. He would be too much for Ahsoka to deal with. Both of them use similar styles of combat but what this really comes down to is the fact that Krayt is simply more powerful. He has mastered both the light and dark sides of the Force which is pretty insane in itself. Darth Krayt wins.
