Why do you chose samsung,not iphone?

I have used iphone4 for 2years,now I use samsungS3,and compare it with iphon5 when I had it.it is more fast in loading the webpage on SIII than that on iphone5,but on the contray ,iphone5 do well in opening app ,more fast than SIII.

So I chose the SIII for having good time in surfing.
