Frank - I mostly use Canon's DPP and at that, not the latest version lol. I do have a legit copy of Phase One's Capture 1 Pro (just updated it to the latest v5), but I'm not really a fan of Phase One as a company and regret buying it. Canon's DPP does 99% of what C1Pro does, in far less time, and in a far more logical UI imho. Don't waste your money.
I've never really used Adobe RAW, doesn't do anything for me.
RAW Therapee (
http://www.rawtherapee.com) is free and works pretty well with most RAW formats. If you're using a Canon DSLR get out the disks and install DPP imho.
