A fight between Naruto and Sasuke would likely be very close, as the narrative and seriousness of their relationship have always emphasized their relative strengths. However, some say that Sasuke is currently stronger than Naruto.
Here are some details about their strengths:
Naruto
Naruto has a stronger version of sage mode that he can use for longer than he could before.
Sasuke
Sasuke only has EMS and has taken a big hit. However, he can probably still use the perfect sisano.
Maybe this will help you choose who would win and not just by favorites.
