I've used DFH since it was released a couple of years ago, and I've recently switched to DFH Superior, and I can only add to what Gorilla said in his post.

DFH Superior is by far the best drum sampler out there. Forget BFD, nothing matches Superior. The sounds themselves are fantastic, and the whole leakage/direct matrix is a touch of genius. It actually feels like you're tweaking a real drum kit, the way all the drums bleed into all the other mics.

IMO there is no contest. The interface is a tad buggy at present (it was only released a couple of weeks ago) but you can work around it and I'm sure it will be smoothed out shortly.
