Boruto is arguably better because it’s allowed to keep going, whereas Naruto ended abruptly.
While I can understand that people might like Naruto more than they like Boruto, it’s worth considering one point: the manga/anime ends with the anime at episode 220 and chapter 700. So while Naruto had 2 hours a week for many years during its run (with film releases), Boruto only has 5 minutes per week (plus full-length films). But what do you expect when Shippuden airs on TV before Shonen Jump does? It would have been much worse if Shippuden aired in 2008 – almost 14 years ago!
