Saw the mic drop example you posted so I'm assuming you're talking about on stage, not his personality.
It's pretty accepted that Jin has the weakest stage presence in the group. And he doesn't really fit their heavier hiphop and hype/badass concepts but I think he's fine in most of their comebacks. Mic Drop might not have been his best comeback but I think he stood out in Butter for example.
I agree. His phrase "Ooh when you look in the mirror, I'll melt your heart into two"... that was so good! Goosebumps! Gosh...
