Vegeta may have become good and started a family in DBZ, but Dragon Ball Super took his character to a whole other level many times over.
The vast majority of fans might prefer Dragon Ball Z, including its depiction of Vegeta, over Dragon Ball Super, but the Saiyan Prince experiences much more growth as character in the franchise's latest series after the defeat of Majin Buu.
Undoubtedly, what fans point to as definitive proof of Dragon Ball Z's superior portrayal of Vegeta is his overall shift from a villain to hero (although begrudgingly), a change that's later underscored by his constant struggle with having to befriend Goku, always leaving Vegeta in second place. But as a hero, he demonstrates something equally shocking. He not only creates a family with a woman no one suspected at the time, but even sacrifices himself to protect them from Buu. Then after his death, Vegeta adopts a more laid-back approach towards his rivalry with Goku by not insisting on fighting Kid Buu first (instead deciding by chance through the game of rock, paper, scissors).
Although masterfully portrayed, Vegeta actually undergoes more existential crises in Dragon Ball Super. Despite the fact that Vegeta had already begun to relinquish his need to surpass Goku before Super, the franchise's latest series sees him gain a new obsession - to get stronger his own way. When Goku achieves Super Saiyan God, Vegeta is able to obtain godly ki by skipping right to Super Saiyan Blue (which is essentially the super form of Super Saiyan God) and then sought to remedy the fact that he had copied Goku by unearthing something new, Perfected Super Saiyan Blue. Vegeta later continues this pattern by avoiding Goku's Ultra Instinct altogether, as this was Goku's technique, and invents Ultra Ego instead. But as Vegeta held onto these ideals, he sacrificed others that he had refused to give up on, including his obsession with training alone and not learning "parlor tricks" like Instant Transmission. In his pursuit of defeating Moro, Vegeta goes so far as to learn from the same species that taught Goku Instant Transmission to essentially master his own parlor trick. But he doesn't stop there. Next, he not only adds Instant Transmission to his repertoire but even uses it.
