Rolo was a ******.
I wanted to see Lelouch stand together with Nunnaly while Lelouch would insult him and kill him.
Just saying.
And I'd say Light for this one.
Only reason Lelouch could do what he did was because he had way more possibilities than Light.
I'd say Light is the better textbook genius and practical thinker but Light has no experience in warfare unlike Lelouch.
But not to mention........ Light isn't a prince of the ruler of the world in an era where there is extreme racism against the Japanese and a ton of flying fighting robots.
Lelouch had more opportunities to do what he did whereas Light was just a regular man, only thing ''special'' about him was that he was the son of the chief of police.
Possibly, I agree that Light is more of a textbook-style genius, but not smarter than Lelouch practically.
Having more opportunities does not necessarily mean one would have an easier time. In a game of chess, when the match enters the late game, some find this a more difficult part of the game against more skilled players/computers because there is an easy chance to misplay and get outplayed.
Lelouch had an open field of possibilities, but many of them could have easily led to defeat because it's easy to make a mistake against such a strong opponent with so many choices, such as when he had to be bailed out the first time he fought Cornelia.
When Light had the open field, he immediately got singled out by L, and then his choices were limited, but focused and small in scale. Defeating L.
True though, Lelouch was lucky not to be japanese in the show, and his connection to his father and mother later did help out. Lelouch did have more circumstance in his favor, but Light required no such privilege in my opinion given his obstacles and the nature of the Death Note (his solutions will always have to kill somebody.)
Light is going to smoke Lelouch in a standardized test and logic puzzles any day. But I do think Lelouch has a stronger capacity for large scale practical situation, most notably whenever Light tried to branch out to the world in season 2. His people (Forgot their names) were so disorganized and loose in their practice, that Light became the only control he had in his chaos, which led to the mistake that killed him.
Lelouch had no such difficulty in branching out under secrecy, and maintaining perfect coordination with his group. I think it was because Lelouch acknowledged that he needed his followers in the long game and Light viewed them as expendable and lesser, which led to his downfall.
