I own Reason too, but I find very little use for it. Thankfully it was decently priced, if I had blown $500 bux on it I would be livid. The sounds are no better than Fruity--either one can use any sample you want, which is something people NEVER seem to understand. Folks, if you're just using the samples that came with your software, you're going to sound like 99% of all the other users of that software. In fact, I often use the same samples in Fruity that I use in Reason. It is quite easy to use Reason for very basic stuff, and the Subtractor synth is killer, but it sucks as a sequencer. One of the worst interfaces I have ever worked with.
For drum programming, I don't think the two are even close to comparable; Reason supports only the most basic of features. At the higher end, since Reason doesn't support Soundfonts, VSTis, or DXis, the redrum drum sampler has only the most basic controls, and there is no velocity switching of samples in the drum sampler, it really doesn't offer much for drums except to the techno world. If you are doing any type of music that requires dynamic drums or life-like drum samples, a nice velocity-switched soundfont, or better yet a kit programmed in Battery (a VST instrument) kicks Reason's ass all over town.
