Great discussion. I find the BFD drum sounds to be my favorite. I use BFD2 and ECO as needed. My second choice is the NI studio drummer in Kontakt. I really like the kits. I've only tried the Abbey Road 60's drums and just don't like them.
As usual, Danny is on the money IMO. The nice thing about SD3 is that it's real simple and easy to use. For me, the more complicated the interface, the more likely I am to waste time messing around. Once you get into more sophisticated samplers it's hard to back. I really noticed the difference once I started using a drum pad and sticks. The SD3 samples just don't have enough layers.
Addictive drums? Some place in the middle of everything, so I won't spend much time on them unless something catches my ears.
I'm passing on BFD3 until black Friday. Way to many purchases this Fall.
