I recall a few years ago (around 2011) the phrase "holy trinity" being thrown around to describe the size, magnitude and importance of One Piece, Bleach, and Naruto all running in Shonen Jump. Now, with two of those specific publications* ending, this so-called "holy" trinity is no more.
However, there would've had to have been three other manga that were considered something like this before, right? Was there was such a confirmed trinity of manga that ran together?
It doesn't necessarily have to be from Shonen Jump, but the closest unsourced examples from the '90s were Dragon Ball, Slam Dunk!, and Yu Yu Hakusho, which were likely published in a shonen-oriented magazine.
*: This doesn't include Boruto. That isn't Naruto.
