>>34831373The stand arcs in Jump went all the way up to 1999, where it moved to Ultra Jump after that. In that era alone, you had Yu-Yu-Hakasho, Yu-Gi-Oh!, Hunter x Hunter, One Piece, and many others.
Hell, the only "powerlevel" manga I can think of off the top of my head would be Dragonball (which really only relied on them during the Cell saga and some of the Buu saga) and Saint Seiya.
