In that case, I'll point out that C++ Core Guidelines has a rule "Virtual 
functions should specify exactly one of virtual, override, or final".
(http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rh-override)

Their tl;dr:
"
        ? virtual means exactly and only ¡°this is a new virtual function.¡±
        ? override means exactly and only ¡°this is a non-final overrider.¡±
        ? final means exactly and only ¡°this is a final overrider.¡±
"

FWIW, they also have a rule "Use final sparingly" with the note that "Claims of 
performance improvements from final should be substantiated."

    Let¡¯s be clear about what we are discussing.
    
    The choice is not be between ¡°final¡± and ¡°override¡±.
    
    The choice is between ¡°final override¡±, ¡°override final¡±, and ¡°final¡± for 
functions which are both overrides and final.
