In the novel, the only characters clearly able to win against him was the Buddha and Guan Yin.
He probably couldn't or wouldn't win against his former teacher Grandmaster Xū Pú Tí (菩提祖师) either.
I found his battle against Yang Jian, nicknamed Er Lang Shen (二郎神杨戬) inconclusive, given he and his monkey folks were outnumbered.
Fellows who drew with him were his impersonator - the Six Eared Peach Monkey, and the Red Child.
In several battles, his opponents had certain particular weapons (such as the Iron Fan or the stolen artefacts) without which he would have won against them.
Somehow though, Sun Wu Kong wasn't able to fight as well in waters in later episodes.
The near-invincibility and powers of Sun Wu Kong were attributable to several sources.
(1) His origins - He was a divine rock came to life after absorbing the essence of the heavens and the earth (仙石吸收天地之气孕育而生).
(2) The skills he learned from Grandmaster Xū Pú Tí (菩提祖师) at the Cave of Crescent Moon and Three Stars (斜月三星洞) on Mount LíngTáiFāngCùn (灵台方寸山) - 72 Transformations (七十二变) and Cloud Riding (筋斗云).
(3) Rewriting/destroying the Book of Life and Death (生死簿) in the Netherworld (地府).
(4) Eating the peaches of immortality (蟠桃) from the Celestian Gardens.
(5) Eating the golden elixir pills (九转金丹) concocted by Tai Shang Lao Jun (太上老君) in his special brazier (八卦炉).
I don't suppose he got much powers from drinking the wine prepared for the Western Goddess' Banquet.
I will discount his weapon - the magical cudgel, as it is something external to himself.
Though (1) to (5) all added up, which would you consider as the most significant in him being so powerful?
