I've grown DP's WW,Powerplant and Mazar and a few of their other strains. I grew out their feminized seeds however so i can only comment on them. Dont use feminized seeds unless you know they will have an unstressed life [perfect conditions].

The Powerplant is a large producer IMO but not very strong. Not too smelly.
The Mazar is Strong but only mabee a medium yeild plant. Not too smelly.
The WW i found to be their best, Nice and strong and a medium yeild, very lemony in both smell and taste. Though it did stink when flowering.

I wasn't impressed with any of their other strains though i have not tried their Blueberry yet. I plan to throw some BB into my next grow, mabee 2 plants. Hope this has helped.
