audio systems

Looking to upgrade to an aftermarket audio system. Looking into the pioneer or the kenwood. Does anyone have any helpful information as to what one is better or if there is another brand that is better. Im looking for a system that has Bluetooth and all touch screen. Considering navigation if it isn't to much of a price increase.
Thanks!!

I bought the Kenwood DNN991HD.
I don't need nav at all, but I wanted all the bells and whistles. (2 USBs, HDMI, etc)
I also liked the DNX891HD. It has a -10db better signal to noise ratio on the CD player than the 991.

The kenwood DNN991HD pairs perfectly with the maestro rr unit and retains sync and steering wheel controls. I chose the alpine double din over both the 991hd and the nex8000.
