I like the look and feel of the 13" more, palm rest on the 15" is too big and that sharp edge digs into my forearms. BTW, both keyboards are the exact same size, even though the 15" looks like the keys are more spaced out.
But the 13" screen is really kind of small, particularly vertically I feel squished when using a 13" screen. I have a 12" laptop (4:3 screen) ThinkPad and for some reason it just feels a lot more comfortable even though the pixel height is the same.
If I traveled a lot, which I do, I'd get the 13", but if I planned on leaving the laptop at home mostly then I'd get the 15".
