Bad pairing, One takes the mission to show us what has happened to the "Hero idiosyncrasy", OPM is clearly a parody of what has been stated to be a true hero and how it entails to bring us a nice time.
But Death Note also takes the "Hero thread" and focus in a typical duel between the Antihero Vs Hero, with much more narrative involved, which to be published in manga, is literally a drag, i didn't enjoy read it, but for sure, i felt how my mind was working and my reading speed began to slow its pace.
Only for the weight that involves in taking the reader to it's world, thanks to the worldbuilding, my vote goes for Death note, even when it feels like it pushes you to like Light or L... and i liked Ryuk more than anyone xD
