It's a tradeoff between raw numbers with the fluffier stuff and I think higher impacts with the wetter stuff. Harder to shovel and it sticks to your car tires and further reduces traction. The first notable accumulating snow we had (the one before Christmas which mostly melted by then) was wet and heavy, and I had to charge the hill out of my apartment building's parking lot about ten times praying my car wouldn't get stuck before I finally made it up to the road. Had the pedal to the metal, front wheels spinning like mad spraying snow everywhere, and moving at maybe 2 MPH.
That, plus spinning out twice this winter on just the thin-packed layer left on secondary roads from snow events days earlier, prompted me to get new tires.
