I think i will need to do more research then. Clearly i've been missing steps and such while "thinking" i knew what i was doing. Thanks guys for the input. For now i'll stick with DPP and PSP X8. One last question. What do i gain by buying a commercial product over DPP? Anything for the basic user?
DPP is an excellent basic raw converter for Canon CR2 files. It won't process any other raw files. The commercial products are all value added products covering a range of additional functions. First and most obvious is that they'll work with most camera raw files. Many of us have more than one camera brand. I want my raw conversion software to process my Canon, Fuji, Sony and Samsung raw files.
Other value added functions include file management/database to varying degrees.
Ease of use and superior interface design.
Local adjustment functions eg. the ability to change only a part of the photo like darken the sky.
Special effects filters.
Special features like HDR processing and panorama stitching.
Superior noise filtering.
Whatever they can think of that might sell.

It's important to understand the fundamental difference between a parametric editor and an RGB file or pixel editor. Raw file converters are typically parametric editors. The original raw file can't be altered and so raw conversion software saves a recipe list of instructions to apply to the raw file and then outputs the result to another file. A lot is possible using this type of editing but notably operations like cloning out utility wires or replacing objects in one photo with objects from another photo are not possible. The pixel level RGB editor is required for that type of work and is capable of making those changes and overwriting the original file. PSP x8 is an RGB file editor that can work at the pixel level on a photo. AfterShot, LR, DPP are parametric raw converters. The two types of editors complement each other.
