Its BIxie Jianfa Gawdammit you guys!!!!
That's all about the power of spirit affect the reality.
GLFW: Tibetan Buddhism
GJ: 9Yin's technique + XL18Z == Outline of Daoism + iChing => (immortal)
YG: Sad Palm + Dugu Swords == extremely emotional + extremely lonely => (human)
ZWJ: 9Yang's technique + QKDNY == Outline of Buddish + Heretics (sentient beings)
In their 30s, 40s, YG may win; the elder, GJ win.
Human beings cannot keep emotion for long, unless they're not human, which might be contradiction.
Even though I like GJ the most throughout JY universe, I have to confess that in 神雕 novel, YG is stronger than GJ at their peak times.
GJ in 神雕 is no longer purely drunk to martial arts. He is rather a middle aged man charged with political and family issues. YG might be stronger the same age as GJ, because YG wouldn't distract as much as GJ, which helps him to practice and improve his power.
Of course, in the 射雕 novel, GJ is much stronger than YG. LOL.
I must claim that to compare-who's stronger debate should be practiced in the same novel. If not, it's very easy to lead OOC.
Well Yideng even never fight anyone after 1st Huashan Duel yet 50 years later he still could hold his own against Jinlun Fawang which mean Guo Jing at the end of ROCH should be around Yang Guo level at best since he is stronger than Pre-HIS Yang Guo similar with Yideng which stronger than Pre-16 years Jinlun Fawang..
