As we know when a Ninja has a Bijuu sealed they instantly get more powerful, the Bijuu chakra fuses with the Ninja making the Ninja chakra grow faster and stronger than normal.
Take Gaara an example, as a kid he was able to kill Chuunin and Jounin thanks to being a Jin.
Take Madara and Obito an example they became OP by being Jinchuuriki.
Take Naruto an example instant regeneration and huge supply of chakra making more training and less resting period.
Before anyone says being a Jinchuuriki messes up the Ninja Chakra control, that was never stated. The only time that was stated was thanks to Orochimaru 5 sealing jutsu nothing more and nothing less.
