Swap iphone 5 for Samsung S3?

I was wondering if i should swap iphone 5 with samsung s3, if i should what's the samsung got that iphone hasn't and if i shouldnt what does iphone have that samsung doesn't. If you get what i'm saying

Iphone has basically everything and is a far classier looking phone.

Just wait for Galaxy S4:) for me i would swap the iphone for an android, because its much better. IPhone can be very boring if you keep on using it.

Don't waste money buying all kinds of stuff, if you know that is trending you will buy it? Not all trending gadgets are very good, apple are always trending but some of their features is so few because of their selfishness, creating iphone 5 and after 6 months their will be iphone 5s that will be 3 additional features than the iphone 5. That is my only opinion to peaople who are wasting money for the trending gadgets.
