This winter I installed a driveshaft and although the car definetely revs faster I'm not sure if it "felt" any faster or not.... Don't misinterpret what I'm saying, I think it's a worth-while mod but again don't expect mind blowing differences.

At the end of the day, some people have had vibration issues depending on what brand of shaft is installed; if I was a buyer again, based on that consumer info, I would likely do the pullies and delete plates first.
