The protagonist's power is very far from Super Buu's power, Super Buu was an equivalent to Gotenks SSJ3 and Gotenks base. After training in the time room, he was stronger than Goku and Vegeta at their maximum powers.
Lol, bro, it's clear that Gotenks is stronger than Goku and Vegeta at most, just as mystical Gohan was also, they were created for that, however, it doesn't say anything about them being more powerful than Goku or Vegeta in base form ( which is what you said), that was the problem.
