That doesn't sound very factual to me. He was able to keep up with TTJ Madara and SPSM Naruto as well as Kinshiki and Momoshiki, the latter even in his advanced form. His Rinnegan-era feats seem to indicate he is comparable to Naruto in speed. There certainly isn't anything to indicate he's clearly inferior.
