For variety you can do both. I've gone up the south slope and descended the north face to keep things interesting. I would imagine that the north face would still provide long stretches of snow for glissading. My only concern would be for traversing a steep stretch of snow that tends to linger on the north side that you have to cross when coming up from the south slope.
If you only want to do one side, I would choose the north slope. I think the approach past all the lakes is prettier, and the climb itself is more interesting.
I would recommend getting up and down as early as possible, though. Prevailing afternoon winds bring in a lot of smoke from a fire that will likely burn until snow or heavy rains extinguish it.
