MS Sasuke and Itachi win. Naruto's FRSs' are easily dodged and Enton turns them into Sasuke's weapons. If Bee can react to FTG, then so can Sasuke and Itachi. Minato's petty 5 second SM is not helping him at all, nor is he superior in any other skills compared to the Uchiha brothers. In CQC he gets obliterated where even Genjutsu is a viable option.
Naruto is done within 5 minutes and 3 FRSs. These two go down easy.
