Yeah... They're just as good as ozone and the conpressor is equivalent to a waves ssl strip.

I'm being sarcastic obviously. It really depends on the sound you're going for or the amount of work you want to do.

Ozone can literally compare your track against another track and dial in a good starting place on a master, and can therfore assure more consistency across all tracks.

Imitation analog channel strips, compressors, and saturation can really add body, especially if they allow some channel bleed like on a real console.

Those plugins may be fine for some styles, but not rock.
