Prove me wrong. I'm a lore expert on Destiny, so odds are I can refute any argument you provide that favors Destiny. Vegeta and Goku would beat the entire Destiny universe in a fight.
Lets also assume they know the mechanics for the VoG and Crota's End.

Of course they would... They flick away beams like nova bomb but bigger the whole series, towards the end almost all of them have some sort of beam capable of easily blowing up the planet earth as they already had that in cell saga. Even a child like gohan could in cell saga. They're 10x faster than anything in Destiny... It would be no competition. All the Titans on earth could put up bubbles and it still wouldn't stop gokus kamehameha from blowing up the planet
