I think they both have pros and cons...
love the outdoor yields but they can't compare to the indoor quality..
So in mho it's a quality vs. quantity issue. not saying you can't grow some fire outdoors cuz I've seen many a outdoor plant that had buds so dense & crazy trichs' it looked like it was indoor. but I'd just prefer the indoor quality, if it's grown, dried and cured right. just my $.02
