In fact, when compared to his former self, when he had the Rinnegan, Sasuke might not be all that far off, but some instances suggest that he might actually be even stronger in some ways.

Sasuke lost his Rinnegan in Boruto, affecting his strength significantly. Sasuke trained his body during the timeskip, gaining hidden strength.

The tragedy of Sasuke's Rinnegan, which was taken by Borushiki during the Boruto: Naruto Next Generations arc —a loss that fans have long mourned—may be resolved by this brief event in the story.

Momoshiki wasted no time in his surprise attack, and stabbed Sasuke in the eye with a dagger. Now, in Boruto Chapter 55, Sasuke confirms the worst: he’s lost one of his major ninja powers!

Even Sasuke’s Complete Body Susanoo and Naruto’s Nine-Tails form can’t keep the shinobi safe from Jigen’s attack, and as stated, the Rinnegan Swap even fails.
