Days of Future Piff
Superstar
Low key though... Goku was struggling to match Vegeta throughout the whole fight, and pushed himself way past his limits the entire time. It wasn't a one-sided curbstomp, you just had two GOATs trading blows, with no telling who was going to actually come out with the win when the dust settled.
That Gallick Gun vs. Kamehameha
Now don't get me wrong, Goku going Super Saiyan is objectively the top 1 DBZ moment for sure... but the rest of that fight went on way too long IMO.
But Goku vs Vegeta might have had the GOAT desperation... Goku couldn't even fight anymore past a certain point and actually NEEDED Gohan, Krillin, and especially Yajirobe to come in the clutch near the end.
