I'll approach this from a different perspective. DPP is only a RAW converter, not an image editor, so it is very simple in operation and easy to learn. I've compared the Windows version of DPP to Adobe Camera RAW (ACR), Raw Shooter Essentials and another one or two. I haven't used Lightroom so I can't comment on using it. I understand a lot of folks use it, and are quite satisfied. I'm sure Marxz is making a good recommendation.
I prefer DPP because it has built in recognition and correction for vignetting, CA and lens distortions for *some* of the Canon lenses. As long as you're not using Vista, DPP will do a transfer of a converted image to PhotoShop after you're done with the conversion.
DPP includes noise reduction, which I don't think works well at all. There are much better NR programs & techniques.
ACR is a good converter as well, I'm OK with either one. I lean towards ACR as I'm using Vista and don't want to convert a file, save as a TIFF and open in PS. When Canon fixes the direct transfer from DPP to PS I'll probably switch back to DPP.
If you've installed the Canon software, you probably installed DPP. You can get the update, if applicable, and try it. The learning curve is very short, and it will provide you with more background to help you evaluate your needs and other programs.
