Both sound great, I have both, but I think that the Ketron SD-2 has the edge most of the time. Especially on the guitars.

MIDI is a subjective thing, though, and if you can, I recommend auditioning. If you can't, I recommend the SD-2. The Edirol is also a bit longer in the tooth, meaning that the sounds sampled are of a certain "era" as MIDI synths go.
