I really think he's currently stronger than BM tbh. Competing against hybrid drunken master Kaidou in base, without even doing a fusion tech of CoC-G2 or CoC-G3, without even any Gear Stacking, without even explicitly showcase Internal Destruction techniques? He's just insanely strong now, now Oda's big homework is for Luffy's mentality. He's like Juggernaut...but with a brat's mentality.
Seriously if he's gonna be this strong currently, imo Luffy should just treat Cracker and Dofla like dis
