enough to make a nice difference at higher RPM, eg: 4000rpm becomes 3760rpm
however, it's not too much of a change to make the lower speeds still doable, expecially in a manual

I did get to ride in a car with a manual that the owner swapped the diff, it was a huge improvement.
If I’m forced to take the 240D on the freeway I just don’t go over 60-65MPH. I admit to the occasional sprint to 75-80 MPH (I hit 84 once, yikes!) to get the hell out of somebody’s way, but it’s definitely not good for me.
