It feels much better in the hand than the S2 simply due to the curved 'pebble' shape.

Also even though the handset screen is 4.8" and the S2 was 4.2" the phone isn't actually much bigger due to the bezzle around the screen being so thin.

Here is a photo of my S3 next to my S2. Sorry for poor quality, taken using my iPad 2.
