I consider both as saviors of Konohagakure...But I consider Minato as the savior of Konoha más than Itachi, because if Minato didn't save Konoha from the nine-tailed fox, a village called "Konoha" won't exist in the world of naruto, and if Itachi didn't save Konoha from the hand of the Uchiha, Konoha will still exist, but in the hand of the Uchiha...
