I bet a nuclear sub would tote a bit more endurance.
Well, maybe not. ; )
Everything I read or hear on the subject says that the nukes are still be best of the best for most comparison categories. The thing of it is, is these new diesel boats are extremely good, and our side had better take them seriously so we can stay a step ahead in both offensive and defensive capabilities.
I believe that our Navy puppeteers understand this. It sounds like the Australian puppeteers understand it, as well.
