I love mature Sasuke. 1st time I ever really liked him, not counting baby Sasuke lol. Usually my feelings ranged from indifference to annoyance. The one time I thought he was cool was during the Chunin Exams final rounds, after he trains with Kakashi. But Itachi showed up and he regressed.
So I do prefer the mature Sasuke. He's still cool and also blunt, but he's more willing to work with others, and give a lesson now and again when he defends Naruto to his bratty son. He seems more patient, shown when he trains Bolt. But that doesn't mean he's not blunt as hell. I also like when he refers to hims as Bolt's master when he tells him "Trust your master." Then his banter with Naruto after the fight is over.
So this Sasuke I am totally a fan of. My least favorite Sasuke is Kage summit.
