More experience? Maybe, but the MC from POMA doesn't learn anything no matter how many times he fights. He's fought so many times, and even with the golden seed, he only starts doing something after getting beaten up, so I don't see how experience helps him in this case. Right now, I can accept that you say he's stronger, but not a better fighter.
Experience is more than just skilled.
PoMa MC had more life and death fight than AC MC had,which is fair since he's older and PoMa has been running for longer.
As for AC MC skills,he's not that skilled yet,his training has flaws he started late and he's quickly catching up but not there yet.
PoMa MC would win imo ergo he's the better fighter.
The advantage that AC MC has is more versatility and he's smarter but that alone doesn't make you a better fighter than someone who is stronger so I don't understand the difference?
If you mean that AC MC is more skilled ,debatable when it comes to fighting prowess,he's more skilled when it comes to non-fighting domains , that's absolutely true.Poma MC is clueless outside of fighting.
