Just so, who is strongest in Buu saga?
The most powerful unfused hero at this time is Gohan and the most powerful buu ever created was super buu with gohan and co.absorbed. Of course if one DOES want to go 10 yrs into the future then its no different. In the cell saga goku said there was no way he could further his base or ssj as in they're maxed out.
Additionally, who is the strongest warrior in DBZ? Goku is our main protagonist throughout the Dragon Ball Z series and by far he's the strongest mortal hero in Dragon Ball Z (excluding fusion forms like Vegito or Gogeta). He is probably the first living Saiyan to obtain multiple levels of Super Saiyan, especially the Super Saiyan Blue in Dragon Ball Z Battle of Gods.
Keeping this in consideration, who was the strongest character at the end of the Buu saga?
1 Son Gohan
The absolute strongest character at the end of the original Dragon Ball, there's just no realistic way Goku surpassed Gohan between the end of the final fight with Buu and the 28th Tenkaichi Budokai (in pre-Super canon at least.)
Who is stronger Gohan or Buu?
There's no way Ultimate Gohan would have even been harmed by the little Buu. In terms of power, Gohan ends up being the strongest warrior on Earth at the end of the Majin Buu arc.
