Yeah.. I've always liked DPP for it's accurate colours, although I've found ACR to be much more feature rich. My workflow usually involves putting everything through ACR, and for the shots which I know ACR won't be able to dish out the goods on (usually due to weird colours), I then throw those particular shots into DPP.
I personally love DPP and I have no issues with my workflow with it.. just that I find it lacks a few features I find critical at times (such as highlight recovery) which ACR (and Bibble it seems) has..
I'll take your advice and download the trial sometime.
