Blueberry can be a bitch to grow, she is a needy girl. The yeilds are not the best with the blueberry I would say average at best but the smoke is killer. So if you are looking for head stash go with the blueberry. If you are new to growing and want a easier plant to grow go for the other ones.
All three are awsome never grown deep purple but it is tga so it will probably kickass.Hope this helps best of luck with the grow and whatever strain you choose.
