Well not having compared AK to these others I was hesitant to say anything, but I run my own biz and really love my AK47...it gets me going in the morning with a couple rips (a little early harvest), but at the same time can waste me in the evenings (truly finished)...I love it! It's my "got to have" weed when I have to get things done, which is ALWAYS! LOL! Ask the busiest stoners what they smoke to get things done...
