For the record:
Chapter: 427 (DBZ 233), P12.3-6
Context: after Gohan and Goten spar a little bit
Gohan: “You’re very gifted at grappling too, Goten! You really surprised me! I hadn’t known you were that good! If you train well, maybe you’ll be able to enter the Tenkaichi Budoukai too!â€
Goten: “Really!? But Trunks is even stronger than me. We play-fight together!â€
Gohan: “Really!? That’s how you guys have been playing?...*thinking* If I’m not careful, I’ll be outstripped…by these little squirts…â€

The image shows them training evenly. Don't give me the "Gohan went easy on Goten" bullshit, because he wouldn't get stronger and fit for the tournament by going easy.
Keep in mind that Trunks and Goten are very close in power with the former being slightly stronger.
They would wreck Cell Games SSJ Goku.
Also, Gohan says "outstripped" and not "surpassed". There's a marginal difference between the two words.
