Alright I am finally finished, after inquisitively went through both stories deeply. I even had help from Gemini Deep Research (yeah ik using ai). I fed it my notes, then I fed the Ai both Poma, and AC full files of all the stories so they can also go through and double check. This is all by feats, and in game lore/knowledge.
I did include game mechanics (mostly for POMA I believe) so if I am wrong about something not being canon lmk. This is the PEAK of both MC's this is Jade Dragon Foundation Aura Clash MC with 2 elements and mastered style. Poma MC did have all Dao's too I believe.
Stronger: Wu Heir
I know, but me and the Ai did the notes calculations of all scenes and TBH Wu Heir Had More destruction ability.
Defense/Durability: Wu Heir
Yeah I know, but once again MC always getting their *** whooped came in handy, the feats they have done (surviving YB Slap YEAH IK) Both Ais I used loved him seriously supposedly he can destroy mountains with slaps. The Surviving all those Peak Houtians was also a feat for this, then the demon execution squad survival.
Versatility: Easily The Thunderfaller, they have so many ways that they can beat you it is really insane, literally Wu Heir does not come close.
Hax/Abilities: Honestly Surprisingly all 3 Ais to my surprise said Wu Heir, literally after reading the story the thought of what Dao/ Golden Seed can do is not the reality, but they still think it carries Wu Heir plus the Devil Breakout. Imo I will give this a tie, but literally just know Golden Seed hard carries by what's it described to do, I am going of lore we were told it's peak capabilities.
Stronger World: Based on the strongest we have seen which is unfair to AC/ what we have been told lore wise Poma is carried by Fraud Wei The Poma world is cosmic in scale yeah carried by a bum, AC is Planetary from what we know in game so far. Plus we have seen some way more powerful scaling from Poma world sadly it takes the W.
Adaptive/Strategy: The Thunderfaller takes this, they have shown way more instances of adapting to bad situations and turning the situation into their favor. NO bs the best strategy MC had came up with is basically running away and waking up Caihong lmao.
Now the moment we all been waiting for...
Wu Heir vs The Thunderfaller at a neutral indestructible arena site: Wu Heir takes this, The Thunderfaller has a few advantages, versatility and Wu Heir being a bum to start off a battle. Thunderfaller has the first advantage rushing Wu Heir putting their backs against the wall , thing is elements become useless, the speed advantages is useless once Wu Heir decides to start teleporting, and Thunderfaller has Flash Step, we have seen what happens when another teleporter tries messing with the void. Dao/Golden seed gives Wu Heir. If you want to see my notes let me know it is explained way better and more deeply analyzed.
