I pretty much think you need to decide which to grow yourself. You did not say which breeder’s gear you are considering but typically hash plant is 100% indica and AK47 is predominantly sativa so you have a major difference in the type of high or stone you will get from each.
 
So which do you prefer, the heavy couch-lock narcotic body stone of the Hash Plant or the intense cerebral sativa high with some body stone tossed in of the AK47?
 
You are sort of comparing apples to oranges so which do you prefer, apples or oranges?
