L wanted it to be Light, because otherwise it wouldn't be nearly as engaging and fun. The only time L tricked Light and got the best of him was with the Lind bit, and that was the only W L had against Light. And even that came in a moment where Light was inexperienced and high off of power. With Light locked in, L could never get the best of him.
What were those instances where luck saved Light?
Also I feel like you're trying to downplay the advantage L had. Imagine having access to every police database, setting up cameras, infinite money and foot soldiers, FBI, technology, the ability to raise a skyscraper in like over night just as HQ, L basically had quasi-omnipotent power and resources to prove that Light was Kira and he could never.
Like I said, L wanted Light to be Kira and operated on that thought process, even tho there was no actual sound reasoning behind it. So then L started going for different tactics to bait Light into revealing himself, but Light managed to outwit him still.
Let's also not forget that while yes Raito had the Death Note, he was playing the game on hard more, because he wanted to live longer. There were restrictions upon Light, cuz if Light hadn't had those restrictions, he could have killed L after their first meeting easily.
Well that's not Light's fault tho. Rem was attracted to Misa and Light managed to remove his 2 biggest obstacles in one fell swoop. He managed to outwit the world's greatest detective and a Shinigami at the same time. Do you realize how insane that actually is. How far ahead and calculating Light is.
Also Misa brought Light more unwanted trouble than actually doing anything good for him.
Well yeah but the Death Note is not invisible and has a set of rules. It's not something Light can do without anyone actually seeing him do it. That's again another way that Light outsmarted L, when eating potato chips, writing with his weaker hand, and killing people while L was watching him and L being unable to see anything off or catch Light in any way.
That's also not true.
When the knowledge was close to being revealed, Light went and
made himself innocent.
By erasing everything he has done, and forgetting about it. So, he plans a few kills weeks before he erases his memories, tells himself that he will be locked up so that deaths will still occur while he is locked up (showing that he is not Kira), understands that L is really good at reading other people's intentions and therefore would be fooled by the oblivious Light, instructs the Shinigami to give the book to a greedy, power hungry individual, predicts that Light himself will be freed of prison due to the lack of proof by L, which therefore leads to himself assisting L in finding βKiraβ, leading to the arrest of Higuchi, which means that the Death Note would be taken from him and therefore end up in Lβs hand, which would therefore end up in Lightβs hand, which then leads to him recovering the memories at the exact moment when Higuchi is being imprisoned, which leads to him predicting that he would utilize the same watch which would contain a piece of the death note that would allow him to kill Higuchi.
Not only does he manage to predict how L and everyone else will react, he reads
HIMSELF into the future, 100 steps ahead. There has not been any instance that L has contrived as meticulously as Light has.
When they do catch Light, Near notes that it was due to the fact that him and Mello together are enough to surpass L. But even then, they weren't actually enough to catch Light.
He predicted accurately what Near would do, exactly. Light, before Near himself thought about it, predicted that the latter would end up deducing that Mikami would be the best fit to fulfill Kiraβs wishes. Thus, realizing that Near was going to change the papers of the Death Note for fake ones, told him to create a fake death note and start annotating on it. All while pretending to not have realized that Light was aware of Nearβs actions.
Had Mikami not acted on his own and killed the woman (which Light told him over and over not to do), the SPK would have not realized that Light had created a fake death note and that would result in all members of the SPK and everyone else opposing Kira getting assassinated.
There are many smart characters in Death Note, but it's made clear that Light stands atop of all of them in terms on intelligence.
