Your sig --> In final battle, technically it will be 4-1 but this 1 will dominate above all 4's of Sasuke...making it something like,I am NOT TROLLING but it seem to me like naruto (the aime ) is like a soccer match between Sasuke Uchiha and Naruto Uzamaki but we donot know the final score till the end of the manga.Let recap on the past score in the series.
1. Before Naruto and sasuke were teamed
kid Sasuke beat kid naruto effortlessly on the play ground
One point go to sasuke
2.Sasuke vs naruto on the hospital
We saw the damage of sasuke power chidori on the water tank,form kakashi view,he stated that naruto did more damage to the tank than naruto .However when we saw several chidori and resengan clashes in part 1 and part 2,they alway do equal damage to each other.
I will say they both tie at the hospital.This score is 1-1 or one point might be naruto but we not sure
3.Sasuke vs Naruto at the valley of the end
We all know who was the victor,eventhough he left naruto instead of killing him.
1 point go to sasuke
4.Sasuke vs naruto at orichimaru base
Sasuke was dominating this battle against team 7 but orichimaru stopped him from using his finishing jutsu(possibly kirin at the moment base one hand movement)
One point go to sasuke
5. Sasuke vs Naruto at the bridge where danzo die
Sasuke was partially blind and faught kages,danzou,kakashi but still was able to counter naruto resengan.
I donot know the outcome if Obito did not interrupted the battle because seem may have lost this one because naruto was not tired .However sasuke could have use some lightning jutsu to finish naruto ,kakashi and sakura since they were on water.Water conducted electricity and they were all in water below the bridge.
I will conclude this to be a tie
Summary
The score is
1-0 before they meet
1-0 valley of the end
1-0 Team 7 reunion at orichimaru hide out
1-1 at the hospital
1-1 at bridge
3 wins for sasuke and 2 draw or 1 one possible win for naruto at the hospital.Sasuke is leading the match!!!!
