@eddz99: Uhm.. no Super 17 is not around SSJ3. When Super 17 first came to be (without absorbing anything) he took on Mystic Gohan/Vegeta SSJ2/Goten/Trunks/Majuub and there where getting tossed aside. Super 17 was so unimpressed by them that when Goten Trunks and Vegeta both landed direct hits..he cleaned his boots (go watch on youtube to see what i mean). Later on he became more powerfull when he absorbed attakcks from Goku. Super 17 at his most basic is well over SSJ3 otherwise he's could't do what he did.
Mystic gohan did not appear in GT and both goten and trunks are still weaker than piccolo. Broly is stronger than Gt gohan, Gt trunks GT goten. So wthose 3 cannot be accounted for in trying to compare theirs to Broly's powerleel as he'd stomp them easily. We do not know how much vegeta's power had increased and as for Majuub well in the Buu saga the original buu's power level(not Kid buu) was perhaps way over goku's imperfect ss3 form and may be on par with Mystic gohan
