also, there would be a massive change in the power dynamic with Vegeta being more powerful than Goku he would most likely decide to make Goku a subordinate and he would take over Earth for the sayains You have to keep in mind that if he became a super sayain in the namek saga he would not have gotten together with bulma so no trunks the power would have gone to his head making him tyrannical he already had a huge ego so that power unchecked would be bad the connon events from dbz wouldn't happen the same way the story would be so far from what we know (sorry if this looks a bit of a mess I'm not the best at getting my thoughts out straight)
Vegeta’s power would have not been enough to defeat Freiza without a significant changes in the Namek Saga, even with his Zenkais. The gap between him and Goku were significant and when he turned Super Saiyan against Frieza, Goku had the edge but it wasn’t exactly a cake walk. Vegeta’s boost would not have been enough and his ego would’ve got him killed against Frieza’s brute force.
Best buddy if Vegeta become super Saiyan and goku might become super Saiyan in android saga
