I'm over here watching dragon ball z blu ray and dragon ball z kai
and a statement that king kai said made me go
when he was training for the sayians goku had a couple months before they arrived but being dead a couple of months meant couple years
so u factor that in
it makes perfect sense why he was able to go ssj3 so easily during the time of peace for 7 years while vegeta wasn't able too
we know vegeta always trained but was already behind cuz didnt reach ssj2 goku had a leg up training with gohan seeing a glimpse of it in the time chamber
7 yrs dead also meant like several decades for him to achieve ssj2 and ssj3
which gave vegeta a disadvantage being alive
so being dead granted goku twice massive power ups first against the sayians then against buu
