Honestly, this has been done way too many times. In fact, Auron Vs. Cloud thread was first created when I joined KH2.net (this forum) back in 2004, and it was the thread that made me join this forum. I joined because I was sick of seeing thousands of salivating Cloud fans ignoring Auron's statistics and details, and just tossing in a vote on Cloud because "HEZ COOL AND HE HAZ A HUGE SWORD LOL".
The fact that is a poll makes it even more biased. People come in and don't even bother to read the debate, instead, they vote their favorite character. In this case, we don't even have to make a poll, the most overrated character of all FF will obviously win this regardless of debating.
I've debated so much on this, it gets tedius having to repeat myself.
Auron: Samauri, best of the gaurdians- chosen for a high position until the temples disowned him for refusing a marriage, so his job was given to Kinoc instead. Strongest sword stats in the entire game of FFX. Cool, badass attitude.
Cloud: On FFVII, was too weak to even get accepted into Soldier. After some confabulation and help from other part members, he managed to make it through the game in one piece. His attitude consists of sexual confusion- Okay, just confusion altogether. Of the game, omnislash has the most hits and I believe can do the most damage of the game, but the stats cannot be fairly paired with FFX due to exclusively different systems.
Auron > Cloud.
In the case of Kingdom Hearts:
Auron: Could have defeated Hercules, but the spell on him was broken *just in time* and he snapped out of it, and let Hercules go. Hades referred to him as "The baddest and most powerful of all!"
Cloud: Didn't even make the preliminaries of the coliseum, was beat by a kid, and was referred to by Hades as "Suckers like these are hard to come by!"
Again, Auron > Cloud.
