Qui-Gon was more friendlier and talked to Anakin like his equal. Anakin could tell he actually cared for him.
Whereas Kenobi who thought Anakin was this lower life form, just like Jar Jar. He ONLY trained Anakin because it was his master’s last dying wish. Had he not said that, Kenobi would have brought him back to Tatooine.
Kenobi did not treat him as an equal, but rather a student who didn’t deserve it. He would tell his student everything he was doing wrong, but never did he praise him, treat him fair, like Qui-Gon would have.
This calls into question why prequel Obi-wan is such a well liked character, in the first place. In the movies, he doesn’t really become likeable until RotS.
