Yea , they could hold their own. People like Shinki and Mitsuki are they only ones who can really put up a fight in the finals. Mitsuki was about to use SM in the latest ep , pretty sure if he faced Rock Lee , CE2 Sasuke , Neji or Gaara he'd be forced to go full SM as his base would get him killed. The new gen would wipe out every other ninja bar Naruto but would lose to anyone Kishi tagged as a "Monster" back then.
1T Sarada would do well , but even someone of weighted Lee's caliber in base or w/1st Gate , should be able to neg her like he did 2T Sasuke who by that time already had more training than Sarada and a more mature/acute Sharingan. Heck base Lee without weights beats everyone from the new gen bar SM Mitsuki. I dont see the new gen doing well in the finals unless they fight Temari/Kankuro/Shino/Shikamru..
