I'm growing a Sweet Special right now (Grapefruit x HOG x Cream Caramel) and have grown
Dark Devil which was really, really nice both in flavor and potency.
And while I haven't tried any so far, the XXL series from Dinafem is said to be really nice
across the board. Blue Amnesia, Cheese, White Widow, Moby Dick...
Another vote by reputation on the Cream Mandarin....VERY good rep on that strain.
I have to say, you can't really go wrong with any Sweet Seed offering and the XXL series
grows that have come in are all pretty positive.
