Well both Naruto and Sasuke have a bunch more power ups imo... because the series will end with these two as the strongest ninjas of all time.
ms = sage mode
ems=kyuubi mode
rinnagen = bm naruto
perfect soosano= bm +sage mode combined
ems = km
bm = rinnegan + ps( because naruto has sm, km, and bm clones)
bm + sm > rinnegan + ps
