Both resorts receive similar annual snowfall, so you can expect comparable snow conditions at either.
4 Vallées has a slight edge in beginner-friendly terrain, with a bit more dedicated green-run acreage.

Keystone Resort's higher base elevation helps snow stay cold and dry longer, giving better conditions through the day and into spring.
4 Vallées has more beginner-friendly terrain and is a lower-pressure environment for new skiers.
4 Vallées wins on the stats that matter most for experienced skiers: more mountain to explore over a full week.
4 Vallées is the better pick for beginners. It dedicates more of its mountain to green runs and easy terrain, which means less time hunting for appropriate slopes and more time building confidence.
4 Vallées (600 cm/year) and Keystone Resort (635 cm/year) receive similar annual snowfall. Neither has a meaningful snow advantage; other factors like aspect, elevation, and grooming matter more day-to-day.
