If it's before Buu got serious then it doesn't really mean anything. Buu had regeneration but he fought against a Basil who was further powered up and he actually said he was more powerful.I don't see how this was a retcon considering that Gohan was doing better against Lavender than Buu did against Basil before he got serious. Even then, Buu got ahead thanks to his regeneration. Finally, we don't know how Lavender and Basil's power compared since they can't be sense.
Super Saiyan Gohan had an edge against a non powered up Lavender. There's not going to be a vast difference between the two. There's not going to be one who people were saying was maybe Perfect Cell level and then two who are considerably above Super Saiyan God.
Lavender certainly isn't anyway because he was beaten by a Gohan who is currently weaker than Buu saga Mystic Gohan.
For Goku and Vegeta perhaps back then anyway. Who knows how it goes now. He was seemingly God level at one point but now he's about as strong as Base Gohan.Base Saiyans crush Piccolo.
He was going toe to toe with him. This was when he only just went Super Saiyan aswell when the poison was only affecting his eyesight. The poison was affecting Gohans health but we don't know if he was actually losing power, that wasn't said.Lavender isn't anywhere near the Super Saiyans
