A wider track on your wheels will give you less traction in the snow, if you are comparing two wheels of different sizes, both running on the same make/model of tire.
Honestly, this is all dependent on the tires you are running during the winter. If you are using all-season/winter rubber, the 20" wheels shouldn't behave severely different from the 18" ones. The only real difference wheel-to wheel would be the unsprung weight, in which case a heavier wheel is of greater benefit when the road gets snowy.
