Alan, I agree Capture One does a good job, however I still find areas where the finer details are mushy at times. Greens especially. Capture One's base profile IMO is a bit off the hue for blues but that's an easy fix with Capture One color controls. I also read where Adobe is working on a better solution for raw conversion. Hopefully they will pass it down to LR and not just CC as I am not a CC user. CS6 has all I need for now.
I tend to lead with Capture One, and only go to Irident when I find an issue where I can't get the look I want. The files pack a ton of details. When I use Irident, I only make the base conversion to tif, then go to LR to finish the look I want.
Both LR and Capture One have a much great tool set than Irident from what I have found.
