Unfortunately all you'll get here is 100 people telling you their favourite brand(s). I wish there was a torture test or something for snowboarding outerwear (like they used to do with jeans).
Personally I've got a Planet Earth jacket that's lasted me at least 10 years. I have probably 200 days on the slopes, and a lot of general winter jacket usage out of that jacket.
I bought a Westbeach jacket/pants combo a couple seasons ago and the stuff is very good, but it's also very expensive ($250 for each piece for a shell).
If you want heavy winter gear get fully seam sealed, 20,000k, etc etc etc. Everything else is subjective methinks.
