I basically use the basic Sonitus plug-ins that come with Sonar for delay/compr/EQ/etc. but the reverb that comes with it is absolutely terrible. I use Freeverb2 and impulses for drums, but I'm in need of something good for vocals.
I mean the EQ is good enough and I prefer it over others just because of how easy it is to use. The compressor is a bit bleh (the limiter on it is awful), but the reverb is terrible.
Sontius compressor is fine but nothing special, the EQ is fine, but the reverb is shite unless you play around with it for way too long. The rest of the sontius bundle is fine aswell. They arent shite but arent great either.
