Besides the Sour D and Cheese varieties...I would have to say Fruity Juice (aka Juicy Fruit) stank to high heaven, wonderful fruity zest overpowered by rubbery/haze tones.
Of course top-notch kush varieties would be on the top of the list.
Sour Candy from G13 labs also freaking stank!!
Most of Reserva Privada's kush gene's, however, STINK.
