Jinsnug has been said to hold his own againstn CC but in practice that has not happened. Kallavan hard countered him for the most part. Lyborick I would argue did better against kallavan than jinsung did. jinsung didn't have much of an edge against pudily in close quarters. Jinsung can probably punch above his weight class using his tiger dragon floral butterfly but otherwise to me it's difficult to suggest he'd even tie with the known corp commanders (kallavan, lyborick, yaratcha). Lyborick was able to stop a punch from kallavan with his bare hands... even jinsung didn't come close to that.
