The entire Jungfrau region (Murren-Wengen-Grindelwald) is super scenic and Alpine cute. But there are some real negatives: low elevation, low snowfall, really really disjointed, bottlenecks, some older lifts & lines, almost no expert terrain and generally expensive unles slumming it in Interlaken. Not a bad experience - just one not to be repeated. >>> I would rather visit in the summer to mountain bike, hike, etc.
Big White/Silver Star/Sun Peaks. They are all OK - uncrowded, mostly average-sized, cut-trail intermediate hills with some alpine areas (very prone to fog), decent lifts and small base developments. Nice, but nothing too special. If you are going to inland Canada/NW USA - I think Schweitzer, Red, Fernie, Big Mt are much better, interesting places with steeps, drier snow, & funkier towns.
