To me, it sounds like Vegeta judged ki against Kibito (he had greater ki against Cell) and effort against Dabura (he fights like an idiot; seems he's gotten rusty).@Hector
And even then you deny all of the statements refering to power just to add your subjective opinion on it, which is the case on here. Gohan was at full effort and full ki/power, I don't know how this benefit your case at all.
Are you playing stupid or something?
Isn't all of Vegeta's expressions supposed to tell us that Gohan against Kibito is as strong as Gohan against Dabura?
You have to be blind to have not realized Vegeta's attitude towards the whole fight with Gohan and Dabura.
