If you have a fat girlfriend, lots of bad tattoos, and like 24 oz. buds and fist fights just as much as you do actually snowboarding, then go for it.
In all seriousness, the vibe at BB/SS is way better (for me at least), and you get a lot more time on the snow. On the other hand, I actually think the snow can be better at MH, at least when it starts to get warm. I say that because even when it gets into the 50's during the day, it gets down into the low 20's at night at BB, and that snow gets harder in the mornings than any snow I've ever seen, and I grew up night-skiing back east.
