1. Luke Skywalker
2. Obi-Wan Kenobi/ Qui-Gon Jinn
3. Yoda
I can only think of four, actually. Luke is first because he defeated the hate within him and fought for good when his situation was infinitely more dire than Anakin's ever was, yet Anakin still fell to the Dark Side. His actions saved the galaxy and his father.
Second is Obi-Wan because he was always the perfect Jedi. Wise, strong, diplomatic, humble. Qui-Gon Jinn also because he discovered how to retain one's identity in the Force after death, and also the Chosen One.
Yoda is third for similar reasons to Obi-Wan's, but in the prequels he seems to be more conservative than Obi-Wan, which was the Council's downfall. But he did finish Luke's training.
