Which is better, iphone 5 or s3?

I've got the iphone 5 but i've always wondered wether i chose the wrong phone as the s3 seems like a better phone, i do know that the iphone 5 has a more powerful processor, packing more up and down speeds, but the s3 seems to have tons of widgets and other tweaks which seem to over take the apps you can get on iphone, i want a detailed answer explaining your views please, and thanks a lot!

The S3 is faster and has more customizable features, along with more apps and less limitations.
The iPhone 5 is very limited and less customizable, and slower.
Please give best answer!

This is a simple answer. I committed the mistake of selling my Galaxy note to get me a iPhone. I end up paying 799.00$ for the iPhone. A week later I sold it for 700$ just so I can buy me a Galaxy note. IPhone its just a Brand. Android are the real movement. They have more speed. No limitations. 99% of the apps you get them for free. IPhone you need to pay for everything. IPhone there's a lot of videos and webpages you can't access, on my android (Samsung galaxy note II) I have no limitations. Apple just spend billions of dollars on marketing just to promote the iPhone. But true is " Its not the biggest thing "

I give you the suggestion to wait for S4. Or if you need the choice from IPHONE 5 or S3 i will strongly recommend you S3.It has more features than IPHONE 5. I'm also telling that IPHONE 5 has less features than IPHONE 4S OR 4.
