Better sound deadener for cab: Spray in bed liner or Peel and seal?

I'm still putting my truck together but the first thing I did after all the floor patching and welding was spray top and bottom of my floor with bed liner and spray up the back on the inside almost to the back window

I plan on using the peel and seal as well, and topping it with fresh jute padding from the hardware store as well. My jute was wet and nasty from years of leaky old weatherstrips.
