I own the Standard version and I use the compressor on the 2bus very often. I really like pushing it, coz it adds some nice little dirt to the whole mix. They are CPU-hogs though... I use the EQ sparingly and do not use the limiter nor the clipper, because I have Stillwell's Event Horizon+ doing this job for me. These things are not transparent ones, but as I said add some dirt and crunch which I find useful. Therefore you cannot compare them to e.g. the UAD Precision series.
I have heard great things about the plugins of the Deluxe version (Pultec and Fairchild emulations, which are available as standalone plugin-versions as of yesterday). But I am on PTLE, so I need to check if they introduce latency (I guess so, because the standard version does) ;-(.
