It's much more solidly in "luxury quiet interior". Under heavy acceleration you can't tell it's a diesel and the only real sound is the transmission/tires. With the '14 you can hear the engine and tell it's a diesel (but do have to listen carefully). When my dad first got in ours he didn't think it would make a difference. After a short drive he admitted it makes a big difference.
Is it worth it to everyone? Absolutely not. To us, we love it being quieter.
Thanks for the feedback. The quietness factor is important to me although when I drove a 2014 Summit (3.6L) back to back with a 2015 Summit (3.6L) over the same route, I couldn't tell much difference. The roads I was on were smooth though (and only a short highway section) so this may not have been a good test. Also, in reading the wk2jeeps description of the active noise cancellation, it looks like the system acts on the engine and exhaust noise at highway speeds with eco mode on. I don't know if I had the eco mode turned on during my test drive. I was hoping the active system would also dampen road noise but I'm not sure that's what it was designed for. Given the description, I could see it making a bigger difference on the CRD model.
I think I will look at the 2015 model a little closer. Thanks again for your feedback.
