I have had both, and I'm primarily a CW operator.  I live in a 
relatively noisy environment.  My experience has been that the KDSP2 is 
much more helpful, because it provides noise reduction in addition to a 
narrow filter.  It is also much more flexible, providing many more 
bandwidth options.  Although I haven't tried it, I understand that the 
automatic notch filter works well on SSB.  I think the reason they still 
sell it is that it is much less costly than the DSP.
