Goten is powerful for his age, but Vegeta his a lot of experiece with battle tactics and enjoys a good fight. Sorry Goten....you lose this one.

vegeta duh goten has only taken the super sayain and vegeta is already super sayian 4

Vegeta wins coz he is older, more experinced n trains everyday
n goten simply stops training after fight with buu
if goten also trained, vegeta is no match for him
