For some reason I feel like because the canon software is specifically made for Canon cameras it should produce better results.
When working with RAW files there is no "right" result and even the determination of "better" can be individual and subjective. The photographer whose only editing is to "adjust color temp, sharpness, and trim the images," may not have the same demands and expectations from a program as one who does more editing. I love editing and (being retired) have the time to indulge myself. Two years ago I migrated to LR2 from DPP because I frequently went to a second editor after DPP and LR offered the tools to stay in one program most of the time, although I thought neither program, within the parameters of what DPP does do, was clearly better, only different. However, with the appearance of LR3 last year I became convinced that, for me at least, LR even at the most basic levels, without considering the additional tools, provides the images I want.
