Regular AP is better than I am at staying centered, keeping ever vigilant, keeping a constant speed, and is also smoother in a number of braking scenarios (many but not all). It also *always* uses it's turn signals when changing lanes (better than most people).
I'm better than NoA in deciding when to change lanes and at picking the right speed when exiting highways. Both of its main features.
So I currently don't find any benefits to NoA, in fact, for me it's a net-negative because it causes more stress trying to guess what it's going to do next.
However -- I use vanilla AP every day and LOVE it.
[CR basically said this, but in a much more negative way, and (as far as I saw) didn't point out the positives of vanilla AP]
