I dont get it saskue was trained by elites growing up and had the advantage over naruto.... and naruto still caught up .... saskue was given the curse seal , witch was he best power up until he was given the ms than ems .... he didnt earn it it was simply a gift ..... Naruto could never go beast mode with control back in his days so it wasnt him .... saskue gets full control of the curse seal witch he didnt have to train for ...... Naruto had to earn his power ups and control of kurma .... and than saskue gets a transplant for ems now he is 10x stronger ...... i look at it this way naruto was given the 9 tails but he is only person alive to control it thats true power not barrow ..... saskue had to rely on itachi and orochimaru for the source of power to me this is barrow power
