It set the tone for a lot of shonen but it's only 2022 lol to say of all time is a reach and this is coming from an og childhood fan. The main series is far superior than it's spin off's and arguably better than its contemporaries at the time, but the latter all comes down to personal preference. I think another question to consider would be how much impact on popular culture has it made compared to other anime? Things like making hands signs, head bands, running with your hands behind your back. I can confidently say Naruto is one of the most culturally impactful anime of all time.
