Light had more obstacles and disadvantages than BB had even with the Death Note, and he still managed to avoid detection for longer. BB was brought to justice without L having to show his face, but Light forced L to reveal himself and ended up beating him.

I believe that Beyond Birthday is way more intelligent than Light is. The way he hid the message in the first murder is one of the most intelligent things i have ever seen and it kind of reminded me of Light when he made his victims write the suicide letters, but what Beyond Birthday was undoubtedly far more impressive, the only thing that Light did was to make the criminals write 3 letters that when you rearrange them and put them in order they spell << L did you know that Shinigami love apples>> while Beyond Birthday draw Roman numerals into his victim's chest that you also have to rearrange,took two volumes of Akazukin Chacha knowing that combined they had 376 pages and he either put or knew that Believe Bridesmaid had a book with the same amount of pages as the volumes and when you find the order of the Roman numerals you turn to the page of the number and you find the first letter of the page and then when you find every page's letter it spells <<Quarter Queen>> which was the next victim. And there are other impressive thing that Beyond Birthday did in the next victims but I am not in the mood to write them because it will take a lot of time.
