The Type 093B is featured with VLS and pump-jet, these things were not seen in the SSNs during the Cold War, even the latest LA class only acquired these features after the modification.
Before the deployment of WS-15, I agree that J-20 is inferior to F-22.
As for Type 055 and Zumwalt, both features with the dual band AESA radars and a new hot/cold VLS. But when it comes to the stealth features, I do agree the Type 055 is more conservative, but China deliberately done that on purpose, since Zumwalt has put too many pre-mature technologies, while China is looking for more sustainable cost control.
To sum up the comparison between 1000/055/Flight III
Dual Band AESA Radar: 1000 = 055 = Flight III
Stealth Feature: 1000 > 055 > Flight III
Firepower: 055 > Flight III > 1000
