I think my Roland Jv1010 beats the VSC, but probably the sounds are quite similar.
I think the Ketron SD2 I have might beat them both easily in most categories.
And my Roland W50 that I played for years worked well as a hardware synth.
Now my Korg synth has some great sounds, but I use the synth to play along, and RealTracks and RealDrums, which make a great auto accompanyment solution.
Midi playback is ok for a track or two in some cases, but to my now deaf ears, RealTracks provided by
www.pgmusic.com exceed the ability of midi to make good, real backing tracks in most cases.
