Tailed Beasts are incredibly important to the overall world of Narutointroduced in the very first chapter by Masashi Kishimoto. Over time, the author continued to develop the concept of these mysterious beasts, especially in the second half of the story. Tailed Beasts are incredibly powerful creatures created by the Sage of Six Paths, Hagoromo Otsutsuki, on his deathbed, when he split the Ten Tails' chakra into nine different parts and used the Creation of Everything to bring them to life. Since then, Tailed Beasts have been incredibly important in the Naruto world in various ways, most notably through the Jinchuriki.
At the end of the Naruto series, it was Naruto Uzumaki who went on to befriend all the Tailed Beasts, and it was pretty clear to see that he was the best user of their powers in the story. Now in Boruto era, things have changed quite a bit, and even better users of Tailed Beast powers have appeared, such as Jura.
Naruto Uzumaki was the best tailed beast power user in the original series
Naruto was the Jinchuriki of Kurama in Boruto
Naruto Uzumaki was born on the fateful day of Obito's attack on Konoha. To stop this attack, Minato Namikaze, Konoha's Fourth Hokage, had to seal half of the Tailed Beast inside his son, while taking the other half with him. Naruto Uzumaki gained the power of this Tailed Beast to control later down the line. However, Kurama caused immense pain and hardship to Naruto in the early parts of his life. It wasn't until Naruto fully earned Kurama's respect that the tailed beast willingly cooperated with him and became his friend.
But at the end of the day, Naruto went on to overcome his hatred and befriend him. In doing so, Naruto also proceeded to befriend all the other tailed beasts, all sharing some of their chakra with him. In other words, Naruto became a pseudo-Ten-Tails Jinchuriki in the Fourth Great Ninja War, where he reached his peak as a shinobi.

As for the Naruto series, the Jinchuriki was almost unmatched, especially Naruto. No other Jinchuriki in the series could beat him, and combined with the Six Paths Powers, even Ten Tails Jinchuriki like Obito and Madara couldn't come close to him. Naruto's use of Tailed Beast powers was far better than anyone else, and he understood this ability best. But all that has changed significantly in Boruto series, which has introduced a new concept of Tailed Beast powers through Human-Tailed Beasts. Now even Naruto's Uzumaki is obsolete compared to these individuals.
Boruto introduces new concept of human-tailed beasts
Himawari and Jura are human tailed beasts
The Boruto series has introduced fans to many new powers, and quite simply one of the most exciting abilities it has revealed is an upgrade to the power of the Tailed Beasts, which comes in the form of Human Tailed Beasts. Previously, Tailed Beasts and humans were two separate entities, and when a Tailed Beast was sealed inside a human, they became the beast's Jinchuriki, or in other words, a vessel.
In the Boruto series, things have changed significantly in this regard, starting with Jura. Boruto showed the concept of Tailed Beasts incarnating themselves as humans through Jura. The current strongest villain in the Boruto series is actually the incarnation of the Ten Tails themselves. Jura is not an individual within whom the power of the Ten Tails resides, like Madara or Obito. Instead, he is the Ten Tails themselves in human form, making him even stronger than the Ten Tails Jinchuriki, and one of the most powerful individuals to have ever lived.
The concept of human-tailed beasts is quite complex and it is not exactly known how it came about in Boruto. However, it is clear that the tailed beasts have evolved greatly, and right now their powers are such that they can essentially incarnate as humanoid individuals through unknown means.
Jura is a better user of Tailed Beast Power than Naruto
Jura's powers surpass Naruto Uzumaki
As stated earlier, Jura is the incarnation of the Ten Tails themselvesand this power of the Ten Tails is clearly enormous. Not all Ten-Tails seem to be built equally. The Ten Tails that fans saw wreaking havoc in the Naruto series were very different from the Ten Tails found in the Boruto series. With some of the power of the Ten Tails found in Boruto, Jigen was able to overwhelm both Naruto and Sasuke at the same time. Clearly, this Ten Tails seems to be even more potent, which is precisely why Jura, who is the incarnation of this particular Ten Tails, is one of the strongest characters to ever exist.

In fact, Jura is painted to be even stronger than Isshiki Otsutsuki, meaning that even Baryon Mode Naruto would struggle against him. As such, it's pretty clear that Jura is the best user of Tailed Beast powers that fans have seen in the entire Naruto series, possibly even greater than the Sage of Six Paths himself, who was the Jinchuriki of the Ten Tails at one point.
Himawari will grow to be better than Naruto
Naruto's daughter will continue to surpass him
Another individual who will inevitably surpass Naruto when it comes to using tailed beast powers is his own daughter, Himawari Uzumaki. Like Jura, Himawari is also a human tailed beast. It's essentially Kurama incarnated inside her, and the two are now one. Previously, Kurama simply existed inside individuals as their beast, while they were the vessel. Now Kurama and Himawari seem to be one, although the former still has her own body inside Himawari. This means that Kurama has better synergy with her, and on top of all this, it means that Himawari has the potential to surpass even Naruto Uzumaki.
Don't think you are a Jinchuriki. You are just like Jura in many ways, Himawari. — Kurama
Kurama's reincarnation has opened the door to countless possibilities for the future Boruto series, and it's clear that these humanoid Tailed Beasts are going to be incredibly important to the line. It is very likely that the other seven tailed beasts, apart from Kurama and Gyuki, will also appear in the future for Boruto series, adding to the already exciting development of the story in many ways. If all of them evolve into their own human Tailed Beasts, then the story will be raised to a whole new level in Boruto.
