Them having different methods to achieve great power is alwaysto me. About time
My theory is this, Whis already let us know what their power ups were gonna be when he told us their weakness. Goku is too relaxed when he fights, but he achieved Ultra Instinct which is basically shutting the mind down and letting the body work itself. Vegeta is the opposite, he has a tendency to overthink, so what do I think his power up might be? Something thats gonna let him use his overthinking to analyze every possible move the opponent makes. In essence that would let both Goku and Vegeta reach the same potential but through exact opposite methods. The GOAT rivalry continues
