Which andriod would be better then a iphone 4s 64GB to do a swap?

I have a Iphone 4S 64GB and i wanted to swap to an android, i was looking at a Samsung Galaxy s3, but i have this friend who is really into all smart phones and sometimes he's a bit rude and jealous and he's told me that a Samsung Galaxy S2 would be way better, or even a Samsung Galaxy note 1 or 2 i just don't see how it could be better then the model above it, not sure if hes just saying this to me to be an *** ( excuse my language but no other way to explain him!) i'm a little confused as to which to choose: S please help

Honestly you would be downgrading if you went to the Galaxy S2.

Galaxy phones are really great phones! They all have expandable memory. So you will actually get a phone that has 16GB, but you can expand them via MicroSD cards up to a 64GB. The GS3 and Note 2 have an 8mp camera, multi window (allows you utilize two windows open at the same time) S-Beam, Google Play store and Samsung App store. The GS3 has a 4.8 screen size and the Note 2 has a 5.5 screen size with a S-Pen that allows you to write notes and use quick commands.

Also if you download something called Samsung Kies you can transfer all of your iPhone content such as apps, contacts and pictures right over to your new Samsung device.
