neither
iphone sucks because of ios and its horrid limitations, with old phones getting slower every new loving version
samsung sucks because of stuffty batteries that die way too fast (have you ever had a battery that was at 15% and then was at 1% 2 minutes later even though earlier it was just fine) and stupid limitations placed on rooting with their KNOX bullstuff
i'll forgetin take oneplus or asus any day over those two loving things
