Just to follow up, I've been using Optics Pro 11 for a while now. Getting really comfortable with the DxO interface took a while but I'm comfortable with it now and have only touched ACR (in "filter" mode via Photoshop) a few times.
I think the three Big Things in Optics Pro that have all but eliminated processing in Camera Raw are these: The default noise reduction in Optics Pro is jaw-droppingly good, Prime Noise Reduction is almost mind blowing. The distortion correction, based on a profile that considers both camera AND lens used to take each shot, is excellent. The ability to dynamically "Spot Meter" a shot during post, and DxO's Smart Lighting in general, is amazing.
My basic workflow has always been boiled down to: Exposure, Color, Artistic Effects. I've gone from several minutes of work-time in ACR (Steps 1 and 2) to several seconds of work-time in Optics Pro before exporting to PS for Step 3.
In short, Optics Pro has greatly reduced a lot of the drudgery of post processing for me.
