hashirama's strength is Wood Release, and only Wood Release. Wood Release is unique because it's naturally strong against Biju, as it drains away their chakra. It's why Hashirama could defeat Madara AND Kurama. Hashirama doesn't have to brute-strength defeat the biju, he just binds them with Wood Release and it's pretty much an automatic victory.

Secondly, his healing is so immensely strong because he's also a Senju, of which the Uzumaki are essentially a watered down version. That and his Transmigrancy (body of a sage) makes him essentially immortal to physical attacks.

Naruto in Gaiden easily matched that healing. However, Hashirama was so desired because of Wood Release, not healing. Healing was only a boon.
