28-70 f/2.8 vs 24-70 f/2.8, Is 24-70 much better?

Both Mike and Rockwallaby have mentioned the propensity of the focus motor in the 28-70 to fail. I only wish I'd know that a few years ago when I bought mine.  I still love the lens and the images it produces, but as of about a year ago, focus is only accurate when the motor turns the lens in one direction.  As I use the lens mainly for people, I have gotten used to defocusing my "beast" to the good side prior to each shot.  You may laugh, but what the heck, it still works!  I will see what Nikon wants to fix it, as I would like to keep it.
