Android 17 got hugely powerful in Dragon Ball Super due to his training. He was able to up his power level by a lot. Many people say that Android 17 was not SSB level, since SSB grants full ki control, where Goku can hold back, but the problem there, was that Goku was not holding back during that fight.
The only Z-Warriors in front of 17 in terms of power are Goku, Vegeta, and Gohan, who is confirmed to be Dragon Ball's third strongest hero. 17 isn't far behind though, and would likely give Gohan a tough fight if the two were to come to blows.
Assuredly more powerful than 17 and 18, Android 16 is canonically superior to Android 13, and is apparently near the same power level of Imperfect Cell, who he manages to defeat. Unfortunately, despite his superior strength, Cell would eventually get the upperhand after transforming, decapitating 16.
While 17 and 18 possess infinite energy and were somewhat evenly matched in the Cell Saga, 17 is much stronger than 18 now. Also, though Dragon Ball Super confirms that Android 18 is still stronger than Krillin, the difference between her and her husband may not be as large as it was once believed.
