The clash between opponents of the same level, aside from the diversity and utility of skills, most importantly depends on the attributes.
Take for example the duel between Xiyue and Cheng Xiao.
Both are War God-level powerhouses with Supreme Law, possessing skills acquired from their path of cultivation.
It is true that Cheng Xiao is a genius, but the resources usually available to geniuses are generally only enough to enhance their innate skills to the Forbidden Curse.
Not every professional is a freak like Lin Yi, possessing nearly unlimited skill points to upgrade new skills acquired after successful job changes to the Forbidden Curse Layer.
In terms of skill diversity, Xiyue holds a slight advantage.
She has the additional profession of a Gunfighter, mastering another set of skills.
With roughly equal attributes, when the two clash, it's evident that the odds are more in Xiyue's favor.
If both sides only have one set of skills, then it depends on the attributes.
