Not sure, from what we were told, Ashura bloomed to be equal to Indra eventually, but was later given extra power by Hagoromo, so I'd say (from strongest to weakest):
 * younger son - Hashirama > Ashura > Naruto.
 * elder son - Madara > Sasuke > Indra.
 * overall - Madara > Hashirama > Ashura > Naruto = Sasuke > Indra
