If we think about it. DG9J = best rite?
then we go to WCY etc, they were great, but not as good as DG9J.
go down another generation GJ is strong, but hes the only real master in his generation, jin lun fa wang is good too really only 2 experts. down to YG's generation, only YG and XLN is really gifted...
keep going and we reach HSDS
as strong as ZWJ is, it is clear that ZZR can cause trouble for him "way weaker tho" but her 9Yin is so weak its not funny. that dude who only mastered 12 of HQG's 18 palms was reasonably strong even tho he only got 12 of the palms.
Yang Guo's disciples/daughters were obviously strong compared to outside world people.
we can keep going down, into SOD, DG9swords is probably weaker than it was in YG's hands, tho we dont know for sure. only person who is really strong is DFBB in this story, LHC probably lose to ZWJ as ZWJ is a master with palm techniques.
