Which gives higher raw power? We are not talking speed, stamina, just physical power.
We are comparing the form of the same user: SSJ2 Goku and SSj Grade 3 Goku.
Goku wasn't special. He was lucky. He received the most efficient forms of training. If he didn't go to the afterlife he wouldn't probably been able to defat Nappa
Same. Grade 2 Vegeta and Trunks would have taken care of Cell Jr
heck, if Goku used it he would be able to fight 100% Cell
Grade 2 boost is very high judging from Vegeta’s transformation sequence
