Every different breeder has their strain or strains that are good.
Just browse different breeders online and check their origins and the strains that made them. You'll find gold in many breeders.
Humboldt seed Organization "Blue Dream"
T.h. seeds "The Hog"
Serious Seeds "White Russian"
Brothers Grimm "C99"
DJ Short "Blueberry"
TGA "jilly Bean", "The Flav", (any of his cup winners)
Mr nice seeds "Black Widow" (the real white widow)
Just poke around and see what each breeder has to offer. They usually have at least 1 signature strain.
Personally I think anything exotic genetix related will exceed your expectations everytime.
