The modern Dark Trio in anime is like the spiritual successor to the original shonen Big Three, and that trio is made up of Chainsaw Man, Jujutsu Kaisen, and Hell's Paradise. All three are excellent shonen action series that got lumped together as dark, bloody, and somewhat subversive anime series with distinct horror elements. All three of them have their respective strengths and found ways to stand out in this trio.
