I have a few Marmot garments, my snowboard pants and two soft shells that are the warmest and lightest they make. The Leadville jacket is in the middle since they've designated it M2 softshell.
I've only been snowboard about once so my experience is fairly limited. On advice from my friends, the first time I was out on the snow, I put my heavy softshell on under a shell jacket. I was WAY too warm to be anywhere close to being comfortable. I took off the softshell after an hour and put it back in the car. The same softshell I later used when I visited NYC in the winter. I put a thin wool sweater under it and I was perfectly fine even at 30 deg F. It did not snow at all while I was there though.
I did not own the light softshell at that point so I cannot comment on that; however, the light Marmot softshell is not completely wind or water resistant because it's meant for high activity in warmer weather. For example I use it for my bicycle commute when it's in the low 50s.
Now what I notice is that the Leadville softshell uses Gore Windstopper material meaning it blocks wind or airflow. I'm not sure it would be a good idea to put it under a shell jacket for this reason.
Fit wise, my heavy soft shell I'd say is normal cut or fit. Not baggy, not close. My light soft shell fits closer though.
I have no experience with Patagonia gear, but it has earned the name Patagucci in some circles due to its price as previously mentioned.
