They were equal.
Madara used his eye power to control Kurama just as Naruto uses his body power to control Kurama.
Madara's eyes matched Hashirama's body
They both ran out of power at the same time, they were both in base mode and nearly out of chakra by the end of the fight. Hashi had enough to use Mokuton clone, Madara had enough to use Izanagi, they both survived but Madara could've killed him after using Izanagi if he didn't plan on cheating his death.
