Gabriel Sousa and Hiago George met 7 times on record, and Sousa holds the edge at 5 wins to 2. Both compete at Peso Pluma, and both are decorated on the international circuit, but their meetings ran heavily in one direction once the matches moved to the gi. Six of the seven bouts were contested in the gi, and Sousa took 5 of those. George's two wins came in 2019, one by Heel Hook at Fight to Win 133 in nogi and one by split decision in the round robin at Abu Dhabi King of Mats, Lightweight.

The pattern in this rivalry is that Sousa found ways to win close and grinding gi matches. Of his 5 wins, three came on points, one on a penalty, and one by submission at the 2018 Abu Dhabi Grand Slam Rio De Janeiro. Several of those wins were finals, which shows he tended to come out ahead when a title was on the line. George's clearest success was the one time the match went to nogi, where he closed with the heel hook.

Stylistically the numbers point to George as the higher-volume finisher across his broader record. He carries a 79% win rate over 199 recorded matches with a 39% submission rate of wins, against Sousa's 74% win rate over 142 recorded matches and a 31% submission rate of wins. In their direct meetings, though, Sousa's points-and-pressure gi game decided most of the outcomes.
