Android 17 is so powerful he took over the earth. That’s something that 16 couldn’t do. Taking over the world takes a lot of skills. Not many characters could do it, especcialy not in DBZ world. Android 17 wins.

Android 17 and 18 are very similar. In power some would say they’re about even. But that’s not the case. Android 17 is leagues above 18 and GT proves it. He was even able to stand up to Saiyan 4 Mode. That’s something 18 couldn’t do. Android 17 wins.
