It all depends on which time period, but if you mean all Uchiha in their prime (Excluding things like the Ten-Tails) then an adult Sasuke is obviously the strongest overall. Even if Itachi is smarter, Sasuke is quite intelligent as well, and obviously he became even more intelligent upon becoming an adult.
