I tried snowboarding years ago and never liked the sideways locked in stance. This means you are a total gravity slave. When you run out of downhill momentum, a snowboard is dead weight and there's no way around that.
I don't walk, run, boat, ski, or ride a bike sideways and I didn't enjoy not squaring my body to the direction to the way I was moving. Way to many disadvantages and time spent on your knees or butt. Every time I'm with someone in the BC on a board, whether they are using slowshoes or a split I have to wait for them to fiddle with their board and other gear, can't do any kind of traversing, etc.
That's just me though, YMMV.
