My ranking:
 * Raw power - Sasuke, BUT Madara's would have been stronger potentially if he had done the same, putting Tailed Beasts' chakras into his Susanoo, not to mention IF his Limbo clones could use Susanoo too, then this would mean Madara + several Limbo clones all using Susanoos as powerful as Sasuke's, if not more, simultaneously, bye bye planet... so yes, Sasuke most raw power (shown) but theoretically Madara > Sasuke (likely possible but wasn't done)
 * Itachi - most versatile for sure, strongest defense (yata mirror) and potentially 1 hit KO move if not avoided (sword of totsuka)
 * Kakashi/Obito - second most versatile next to Itachi's, but with more raw power... easily most balanced Susanoo

Canonically, we know nothing of Indra's, Hagoromo's is most likely not canon and Shisui might or might not have been able to use Susanoo in manga canon, but no examples shown in canon, with all appearances being anime filler or games.
