I feel like out of all of these that qualify as true Jedi (tried to adhere to Jedi principle and code) Luke is the one that his pros at least out weigh his cons in a sense . Like he knew his hesitation , hubris , and lack of guidance from an uncles perspective caused him to drive and lose Ben solo to the dark side and tried to fix that without having to put the spiritual burden on Ben if they were to actually have a physical confrontation. He just stalled Ben and gave him words of wisdom. Also him overcoming palpatines manipulation and giving his father that support that allowed him to come back to the light side gives him good Jedi points as well. Obi wan and yoda were too dogmatic and manipulative for me personally . But a great yoda quote applies here and I’m paraphrasing but it’s “ we are what they grow beyond , that is the true burden of all masters “
