My favorite moment was when Goku was going SSJ for the first time and when Gohan was going SSJ2 for the first time. Those really got me. Everytime i see them i get goosebumps. It's the greatest thing ever. Man I love Dragonball. I wouldn't be able to live without it.
When Goku was going SSJ first time i was going craZy
Didnt really appeal to me when Gohan reached SSJ2, i got more excited when he went SSJ
Goku going SSJ3 has always been my favourite moment, i've watched that episode soo many times

My favorite moment is probably pretty obvious. Just in case some don't know, then i'd say it's when Majin Vegeta sacrifices himself when fighting against Majin Buu.
