What you said simply doesn't make sense. "Ambition" "innate talent" "understanding" "relatively more quiet period" and all those garbage buzz words you like to use....as if they got anything to do with who is more talented. Make a sane argument for once.
Garbage Buzz? If my reply didn't make sense to you then I don't know what to tell you. Other people seemed to read it just fine. Just in case:
1) Innate Talent
Innate - inborn, natural
"Innate Talent" only means "Natural Talent"
2) Ambition
Ambition - A strong desire to do or achieve something, typically requiring hard work and determination
Ambition turns to talent given one has the determination to acquire it.
In my opinion, Madara had more ambition than Itachi. You can have two equally talented people but the one with more ambition is going to go farther. Not a hard concept.
3) Understanding
Understanding - the ability to understand something, comprehension
Easily understanding anything in a certain area can equate to talent.
In the way I phrased it, "understanding" it would imply comprehending it on a deeper level like Mozart understood music and Einstein understood physics.
4)Relatively more quiet period
Not sure how to break this one down any more. A time with less war? Which was already implied by the previous sentence.
It had everything to do with who I thought was more talented. I even included a TLDR at the top for people who didn't want to read further. Anything below would have obviously been why I thought Madara was more talented than Itachi.
