(arguing stuff about how Ultimate Gohan>>>Goku and how Goku was afraid of Buu etc)
Gohan is clearly stronger than Goku during the Buu fights(I'd wager End Z Goku was by far the strongest person alive in the series). Goku wasn't 'afraid' of Super Buu, he just didn't think he could beat him.
Goku > Fat/Kid
Super Buu/Buuhan/Buutenks ect, ect > Goku
