Tip: looks like you are not using the correct Gamma and Linearity settings in UFRaw. Set Gamma to 0.45 and Linearity to 0.11 on most profiles, including the built-in sRGB gives you correct output.
Tip2: Download a trial version of PhaseOne and install under Wine. It contains ICC profiles for all Pentax cameras. Extract the one you need (I use K100D Super) and than remove the whole PhaseOne folder from your .wine folder. Use the profile in UFRaw as input profile and output to sRGB, still keeping the Gamma and Linearity settings as per tip 1.

The K20D Jpeg is totally burnt out in the higlights above the eyes - no details left
PPL and RT restore the details and the colour in the highlights
UFRaw and RawStudio have the same burnout as the JPEG, but I suspect you did not use auto-exposure and highlight restore in either.
All in all, you cannot compare raw programs without getting to know them a little and all are made for tweaking. If you do not want to tweak obviously PPL is the best choice together with RT only RT introduces some loss of detail due to the way it handles sharpening and NR.
UFRaw, when used correctly (and DCRAW) will produce results that blow the JPEG out of the water.
Any way you choose is a matter of taste but the gap between JPEG and raw is unsurmountable.
