SSJ3 Goku is much stronger
vegito
no vegito is way stronger i mean in normal he can beat him
ssj gotenks because power level is 1.500.000.000 and goku's is 1.080.000.000 it is 420.000.000 more than ssj3 goku
actually vegito is stronger. 1. the maker(akira toriyama) said so 2. portara fusion is 100X stronger than the metamorphan(fusion dance) 3. SSJ4 gogeta is about as strong ssj3 vegetto- it is believed by many that vegetto can go up to ssj 3 or 4. he can because Vegetto is stronger than goku who is a ssj 3.
manga: gohan anime: goku manga : Gohan > SSJ3 Gotenks > SSJ Gotenks > SSJ3 Goku anime : SSJ Goku > Gohan if you see the filler inside buu Goku say they strong as the real one but still if go by manga SSJ Gotenks is enough for SSJ3 Goku
Super Saiyan 4 Vegito
Well there is no Ssj5 but in there was Vegito would be the stronger one.
gohan because goku ssj3 was same in powerlevel of fat buu and super buu is twice stronger than fat buu and gohan was beating super buu like anything so gohan mystic is stronger than goku ssj3.
Vegetto and superbuu was even in power then vegetto whent ssj and he was 50 times stronger than superbuu, but kidbuu is twice as strong as superbuu, if vegetto was normal, kidbuu can easily win, if vegetto when super, he could easily win kid buu, another thin goku ssj3 and vegetto is deadon even so figure out for yourself, you saw the figth of kidbuu and ssj3 goku.
vegito because gogeta ssj4>omega shenron and vegito base>gogetassj4 so vegito can beat omega easily gogeta was in ssj4 form to deafeat omega and if vegito is stronger than omega in just base form what if he go to ssj4 also like gogeta vegitossj4 will win in just a blink of his eyes against omega don,t remember vegito is strongest off all transformation and person in dbgt,dbz and db.
Vegito, because the Potara earrings are far stronger than that of the fusion technique.
SSJ Gotenks (Pre Rosat) > SSJ3 Goku why? Base Gotenks (Pre Rosat) vs Fat Buu is the same like what the Majin Vegeta Fightso i'm give Base Gotenks = SSJ2 Majin Vegetaand Goku even say to Piccolo Gotenks will be stronger than himself lol even Base Gotenks (Post Rosat) > SSJ Gotenks (Pre Rosat) > SSJ3 Goku
ssj 4 goku
