Its a matter of preference. i like abysynth most. I also dig the sound you can get out Reasons Malstorm, it sounds kinda digital l but i think you can get some very odd/unique sounds out it. I like to play around with FM7 from time to time, not realy into of Pro 53. I think the Virus is my fav hardware synth. Absynth fav soft synth. Although, it does seem unstable from time to time, shit it even makes crazy nioses when it crashes.
