Toji negged Dagon, a fellow Disaster Curse. Toji defeated Gojo and Geto, who were already Special Grade Sorcerors at that time. Jogo’s best feat is him negging a heavily nerfed Naobito, Nanami, and Shibuya Maki, and Maki easily outdid their feat when she negged the entire Zen’in clan
Toji “negged” a Dagon that couldn’t use his sure hit (the strongest part of a domain) and was being tag teamed
Naobito stopped him from levitating which would’ve given him the advantage
Toji defeated a tired Gojo who had kept his CT active for days and hadn’t unlocked CTR or RCT
Young Geto is featless so that’s not really saying much
Jogo’s best feats are tanking red, being put an entire tier above Dagon in power, filling an entire office building with flames without a named attack (unrivaled AOE), having one of the few domains that can deal damage without using the sure hit, etc
Statements also further back up his strength
Gege confirmed that Kenjaku (the same one that beat Yuki and Choso + Tengen) in a 2-3 v 1 would have a tough time against Jogo or Mahito individually
15 Finger Sukuna confirmed that Jogo’s Meteor would damage him if it hit
Kenjaku estimates that Jogo is on par with 8-9 finger Sukuna
Sukuna considers him a strong fighter
There are a number of ways Jogo could beat Toji or Maki
I admit that they can beat him with ISOH but anything outside of that is an L
