Bum Shi is not a top tier general
He would never be a Qin6 or a 3gh or even make it as a Chu GG
He belongs in that vassal tier with the likes of Gyou Un etc who could be a GG on their own but are better off being used by an actual top of the verse commander.
Whether you think he's slightly weaker or stronger to 1st commanders doesn't concern me just know that you are being retarded if you are arguing the victim of a 14 year old Ouhon is out of the league of guys like Gyou Un or Bananji.
Gun to my head i'm taking Gyou Un over him anyday and even if he's slightly stronger (he isn't), Gyou Un has a better army and abilities as a commander and would crush him in a 10k v 10k battle.
