Kenobi Kyle would be better because WE trained him gave him our strengths and made him stronger than any Jedi before him. Luke's lineage gave him an advantage yes, made him strong in the force yes, but could he ever defeat one who has been trained by a thousand masters all over this world.. I think, NO I KNOW that Kyle could defeat this weakling Luke Skywalker anyday. Period.
I AM NOT INSANE.... but my therapist seems to disagree
