Both the new Transmigrants were 16/17 during the war, while their previous ones had reached their prime and had war every in their lives to bring out their potentiel instead of training. As Tobirama, and Orochimaru have comfirmed, they see potentiel in Naruto and Sasuke that goes beyond Hashi and Madara's skills and powers.

Having the Nine Tails or the EMS, is like having a tool, having a tool doesn't degrade them of their powers, it just shows how well they can use those tools. While Hashirama had Wood Release and Chakra beyond anyone ordinary, he's still very subjected to jutsus like Genjutsu, Poison, teleportation, dust release, and various others.
