Moria by far. He's basically a broken down Luffy since he actually cares about his friends and valued their lives just like him. The only reason he created a zombie army was because he didn't want to go through the pain of losing another friend like he did in his past. You can also tell due to him when he was extremely worried for his late friend Absalom when he had the guts to actually enter a Yonko's territory alone (well, excluding his zombie army) and wanted to run all the fade with Teach.
