It's a common misconception that GM has to sound bad. Consumer GM units used the smallest sound ROMs they could get away with, lower quality DACs, etc. But you could fire up GM on your Kurzweil K2000, your Quadrasynth, your Roland, or Yamaha professional level synthesizers and workstations and the same GM programs would sound amazing.
For less than a higher end Sound Canvas, you can get a real professional synth with a much bigger and better sound ROM, better DACs, better effects, etc.
