Skis when going any distances. Snowshoes are labor intensive, skis not so much.

If you can walk you can crosscountry ski.

Used both in Alaska back in the early 80s, courtesy Uncle Sam, who thought I needed to learn Artic warfare. Snowshoes were used mainly, as stated by others - shorter learning curve and with the loads we carried, more efficient.

Before I enlisted, I would x-country ski to work. My car at the time was hell in snow.
