At first, Vegeta and Goku were only friends who fought. However, the second time they met, Vegeta felt the difference in their strength. So, let's explore the relationship between Vegeta and Goku.
Goku's Personality

He's called Goku when he's on Earth, but as a Saiyan, he's called Kakarot. He seems to be blessed with superhuman physical strength and endurance. He is liked by everyone and has a kindness that makes him unable to leave someone in trouble alone. On the other hand, because he has Saiyan blood in his veins, he gets excited when he sees a strong opponent. Normally, I think he would feel fear, but that's what makes him different from others. That's why Goku... I think he can get stronger by training, and there are elements to become stronger. And maybe it's a unique Saiyan way of thinking, or maybe it's just Goku, but he doesn't seem to get depressed even when he loses a fight. On the contrary, he stays positive and seems motivated to train hard and become stronger. It's things like this that make him seem mentally strong.
Vegeta's Personality

He was apparently born with exceptional fighting ability. Perhaps because he's the prince of the Saiyans, or perhaps due to his childhood upbringing, he has an extremely high sense of pride. This is why he hates being criticized or criticized by others. Because of this personality, he often finds himself easily manipulated, which can backfire. In these respects, he's at a disadvantage. He would later regret it. However, it seems he mellowed out a bit after his son, Trunks, was born.
Vegeta Recognizes Goku's Strength

Vegeta, a proud man, refused to accept being stronger than him, no matter how strong the opponent was. He didn't want to admit it, and it would hurt his pride. However, when he is thoroughly defeated by Frieza, he entrusts Goku with defeating Frieza. It's surprising, isn't it? It takes a lot for Vegeta to ask someone for help. On the other hand, it's proof that he recognizes how strong Goku is. I think he can understand this because he has actually fought him and seen how he fights. Perhaps it is because they are so familiar with each other's good and bad points that they are able to trust each other so much.

I'd like to discuss the personalities of Vegeta and Goku. At first, they were merely enemies, fighting each other. Their personalities were polar opposites, and they had nothing in common. Many people probably thought that these two would never become friends or become allies. However, after watching each other's fighting style and defeating other opponents together many times, I think he began to believe in his own strength. Otherwise, I don't think Vegeta would have asked Goku, the person he wanted to defeat the most, to defeat Frieza. Sometimes fighting can lead to friendships where you can trust each other. I hope Vegeta and Goku will always be good rivals, but good friends otherwise.
