as the title says...
who is smarter me or that arrogant from code geass...
i have to give him credit since we have the same motives but my death note surpass his eye power...
but he is a better leader than me i would probably manipulated the green haired girl and most of the people there...
he actually have friends and assist which i dont need
The same motives? Not in the slightest. Sure, both Lelouch and Light aimed to change the world for what they felt was for the better, but it was not for the same reasons in any way. Lelouch did what he did to make the world a better place for Nunnally and to get revenge because of how much the system screwed him over. Light did it because he felt it was justice, though he never had any other person he cared to do it for and only did it for the sake of his own beliefs, to the point where he was driven to insanity.
As for Death Note surpassing Geass, that's VERY VERY debatable. They're such different abilities that it's stupid to compare one as "superior" to another since they're both used for very different circumstances. And better leader? If Lelouch has anything going for him it's insane charisma, which is why he managed to even get the Black Knights under him in the first place. Light never really showed leadership of that level.
And for the record, Light DID need assistance, without Misa and Rem there's utterly no way Light could ever have possibly imagined to take down L. His entire plans to win literally revolved around the help he DID have.
Well they had different game plans.
Light was simply a master of hiding his identity.
Lelouch not only hid his identity, but also was a master of combat strategy and deployment. Combined with his efficient use of Geass he managed to conquer the world and then act like a tyrant in order to bring peace to the world. I suppose it's worth mentioning he never lost sight of his goal.
So really they are both intelligent with what they did, but I'm personally going with Lelouch because he had to hide his identity, take the world, and find a way to die to bring peace to it....though even then it's plausible he actually didn't even die by obtaining Code Geass.
This pretty much sums up my thoughts. The problem with Light is that he descended into madness and not only that but made many, many blunders that could have been avoided if he just wasn't so arrogant. Lelouch definitely made some blunders, but many were unforeseeable circumstances that simply weren't his fault. On the other hand, you have Light with this "ZOMG LIND L. TAILOR MUST WRITE NAME DOWN MWAHAHAHAHAHA" mentality and god complex and anyone could tell how bad that made things.
With that said, Light was far better at keeping his identity hidden than Lelouch.
To be fair, Lelouch had to be on the front lines and actively interact with a large group of people in a world with many more threatening resources. All Light needed to do was sit in a room with a book that had the power to kill people, which in a realistic world seems utterly implausible. Light keeping his identity hidden "better" isn't really a valid point to make, one because the circumstances for that were much better than Lelouch's, and two being that the moment Light's identity is given away he completely loses, whereas that was not the case with Lelouch.
