Looking at the jQuery API (http://api.jquery.com/val/) you can see that using .val is better than .attr('value') simply because the .val() function accepts parameters and you can add other functions to that specific value you're selecting.

Also, "The gist is that .attr(...) is only getting the objects value at the start (when the html is created). val() is getting the object's property value which can change many times."

Nothing.. but val() i guess is just a wrapper (if not another way) of getting the value. I guess because getting a value of something is so common, its nice to have a shortcut (smaller code) than big one..
