leave it standard.
you paid for airbags too are you going to try and use those as much as possible?
bad analogy--airbag is a safety item, not luxury--you will be thankful you have an airbag when the time comes; although you'd wish that you'd never have to use it. DSP is more like the seat heater/cooler--use it if you feel it enhances your driving/listening experience. I personally leave it on because the plain stereo mode sounds kind of flat in comparison.
