It's likely Saitama would win. Saitama's strength is on a whole different level. He can destroy planets with ease. Naruto's power mainly lies in his chakra and ninjutsu. Although Naruto has defeated some very strong opponents, he has always had to strategize and put in a lot of effort. Saitama doesn't need any of that. His physical strength is so overwhelming that Naruto's attacks would probably be like mosquito bites to him.
