Is this actually legit though? All Gohan has done in Super so far is fight a Frieza crony and get
I remember Gohan doing some stuff in the Baby and Shadow Dragon arcs.
He gets one episode of focus in the Baby arc, noticing the possessed Goten and fighting him before getting possessed himself. Then, Baby in his body leads all possessed Saiyans to take on Vegeta in the next episode. There's also his big goodbye to Piccolo, which feels kind of odd considering their lack of interactions in GT up to that point.
Outside of that, all his later appearances were just him attempting to fight but losing to the villains without accomplishing anything. He even loses to Rildo in the Super 17 arc - and aside from that Rildo battle, it was always in group fighting scenes, alongside Trunks, Goten and Uub, never getting any actual focus or screentime.
In comparison, Super gave him main focus for 3 episodes of the RoF arc and he also had that one episode that introduced Baby Pan. Then he had general minor appearances in the BoGs and other episodes of the RoF arc and one episode in the Trunks arc, even if only to show him retired.
He does have less fighting scenes in Super so far, but other secondary characters have more (like Piccolo, who didn't get a single battle in GT). Super has also used Roshi as an actual serious character at times, while GT only had him as a joke. And Tenshinhan and Yamcha in GT were just mute background cameos while they at least appeared in some Super episodes (and Tenshinhan fought) before the current Trunks arc.
