I have both DFH and DFHS (Superior) - the difference between the two is huge. Definitely go for the Superior version, it integrates directly into Cubase as opposed to the other version which you need Halion, Battery, Gigastudio or another of the big samplers to plug into before patching into your sequencer. DFHS acts as a VST plugin so you can program directly into the midi window. You don't have to use Cubase though, just anything that can handle VSTi's. As far as the sound goes, it's great plus it's easy to use and set up (unlike DFH which is a lot more fiddly). Toontrack have another package too that may also be worth checking out, I believe it's cheaper and even easier to use plus it's getting really great reviews - EZ Drummer (you can also get DFH in this format).
