Never really thought of this but i'd say Sasuke without his hatred,which would be the begining and after his talk with the Hokages til now.
To be exact,he always had hatred until he gain his new resolve,but he didn't place more importance on it until He met up with Itachi again in part 1.So begining til then would be #2 for me,in terms of favs,and first would be,current Sasuke.
