technically the samsung phones are more powerful, but I feel like these iphones still run faster because their hardware really seems designed around this specific OS. my step dad has the new galaxy, thing is massive, can't imagine sliding it into my pockets. I went with Sprint on the iphone because ATT and Verizon were ridiculous pricing wise for contracts

I have a 4S, I've never regretted buying this phone. I used nothing but droid phones before hand.
