Fantastic kits abound for it here, in the mag, even our own Kriminal here has cooked up some great kits for it! 
Well laid out and logical for me atleast. And great detail to each and every sound is possible. For a wild example, my 'At War With The Dalai Lama' track in the Music Cafe, all the drums were programmed using the SR-202 (sorry, I forget which kit I had loaded. 
) But that's an extreme example, the SR-202 has Jazz Drums - Ambient Drums, Hip Hop drums, etc. And you're free to make your own kits as well. If you can sample it, the SR-202 can play it. DS-404 is like a 'brainiac sampler' - it's good, but a little to complex for my tastes.
