Ocean Forest, I've heard, can be too hot, dangerously so. When I say "hot," I mean it literally. That stuff can compost to the point of combustion...compustion? I've always used FF brand Happy Frog, and I have zero complaints.
So I'd say pots, unless you're someplace with already pretty awesome soil. If:
a) You're growing autos, which, as already stated, won't veg long enough to develop big root systems;
b) The ground you'll use has less than ideal soil, and would require digging holes and then backfilling with better dirt;
then you could save yourself the trouble of digging holes, which is a pain in the ass, by just filling pots and using those. Just my lazy ass 2 cents.
