Les 3 Vallées edges ahead in more categories, though the gap is close. Both are excellent resorts.
Les 3 Vallées has significantly more vertical: a full run takes noticeably longer and the mountain feels much bigger.

Portes du Soleil dedicates significantly more of the mountain to beginner runs, a much friendlier option for new skiers and snowboarders.
Both resorts are similar in size, so you'll have roughly the same amount of terrain to explore.
Les 3 Vallées's higher base elevation helps snow stay cold and dry longer, giving better conditions through the day and into spring.
Portes du Soleil has more beginner-friendly terrain and is a lower-pressure environment for new skiers.
Les 3 Vallées wins on the stats that matter most for experienced skiers: more mountain to explore over a full week.
Portes du Soleil 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.
Portes du Soleil (700 cm/year) and Les 3 Vallées (700 cm/year) receive similar annual snowfall. Neither has a meaningful snow advantage; other factors like aspect, elevation, and grooming matter more day-to-day.
Les 3 Vallées is the larger mountain by trail count (Portes du Soleil: 286 trails, Les 3 Vallées: 327 trails). On a week-long trip, a bigger mountain means more variety and a lower chance of feeling like you've exhausted the terrain.
Les 3 Vallées has a higher percentage of expert terrain. If you're an advanced skier who will spend most of your day on black and double-black runs, that extra challenge is worth considering when choosing between these two.
Portes du Soleil is generally the better family resort based on its terrain mix. More beginner-friendly slopes means children and less experienced parents have plenty of room to ski without feeling pushed beyond their comfort zone. That said, both resorts have established ski schools, so check current program reviews before booking.
