Round 1- Goku is distracted by Vegeta abruptly leaving his ass for dead, and Ginyu capitalizes on the opening. Goku quickly recovers and returns fire, Ginyu's facial expression to Goku's kick is interesting.
I think they are basically equals, if anyone is slightly superior, it's probably Ginyu. I agree with your analysis Ahill, he estimated Goku and decided to come after him with a power superior to 60k to give himself a slight advantage only to find out that Goku is on that level. In my expert analysis this is what I think.
Ginyu 66,000
Goku 65,000
Ginyu Estimates Goku to be 60,000
Now we can debate what Ginyu meant by Goku being "better than he thought". For me it's simple, he thought he was 60k, after fighting him, he realizes he's even stronger.
Let's get Japanese anime quote as well as Herms quote if possible. Let's knock down Round 1 and move on after this is done.
