Well Zhang Sanfeng himself admit that he’s not at Guo Jing “level” according by Wuji and Wuji though he have a lot of great skill but lack of battle prowess/experience and weak mentality so I would pick Zhang Sanfeng above Wuji…
As for Guo Jing unfortunelly we dont see him in a fight post 16 years ROCH so we don’t know how strong him post 16 years ROCH/end ROCH
For Lao Wantong (Zhou Botong) he would lose if Yang Guo “serious” from the start of their friendly fight
So I would rank
- Sweeper
- Xu Zhu
Shi Potian - Duan Yu
- Xiao Feng
Dongfang Bubai
Yang Guo
Guo Jing - Zhou Botong
Zhang Sanfeng
Zhang Wuji
