pretty straightforward... I use "lite" version of both that came with my MBox. Problem is that I use both for their sounds, and I do both Pop/rock/mainstream music (so, need good bass, piano, orchestra, strings, brass, etc.) and tripped out stuff (synth heavy stuff, loops, etc.) I also know that both do good versions of those sounds. Just wondering which one you guys prefer? Thanks for the opinions and the help!
