First off wrong. They didnt go SSJ in the last Budokai to avoid publicity and its no different this time. Here Ill give you both quotes that state base Goku > Good Buu:Saiga wrote:All that means is that Oob's no ordinary human, and from that Goku can confirm that he's Pure Boo's reincarnation. That doesn't make him stronger than Good Boo.TheMightyOzaru wrote:

Goku: “Oh, I see. You still don’t even know how to fly, huh? …I guess there ain’t no helping it. You haven’t had no teacher, and you probably never even considered things like that. Sorry I bad-mouthed you before. Please forgive me. I just wanted to know your true ability. You’re exactly the person I thought you were. As amazin’ as I expected. But you don’t know how to use your power. This is the first time you’ve fought like this, right? I've got it! From now on I'll live with you at your house and teach you!”
Goku isnt disappointed in the slightest. base Goku > Good Buu. I see no reason whatsoever to assume Goku is weaker than Gohan. As for the SSJ thing, it was previously established that they wont go SSJ during the Budokai.
I see no reason to assume Goku is stronger than Gohan since Gohan was stronger than him in the Boo arc by a fair margin and even though 10 years have passed Goku hasn't been said to be doing any kind of amazing training that would help him close such a gap.
And it was a different Budokai that they agreed not to use Super Saiyan, to hide it from Videl. No reason to keep it that way for this one.

Goku: “…But someone besides us and Boo might win.”
Satan: “Hahhahhah, now really! There’s no way that could happen, right?”
He says Uub might be stronger than all of use and Buu.

Goku's suspicions are confirmed. He is stronger than Good Buu like he expected since he is as amazin' as he expected. Its pretty clear that Uub > Good Buu and Goku >= Uub.
