Fine, fine. Spend hours perfecting knobs on Maximus and other mastering plugins to a fine point. Honestly, does it matter if it's lazy mastering mixing if it sounds good either way?
If it sounds good, it's fine, but you better know what it's doing to your sound. soundgoodizer almost always makes things sound muddy and over-compressed (imo) so use other mixing techniques to further refine the sound. Soundgoodizer isn't a 1-click-and-forget-it solution, and I don't think it was meant as one either.
