A lot of the gun is the same I assume i only have both in the SP-01 line and they are similar in trigger and all basics the springs modifications etcetera the differences I believe is in the disconnector I have heard some places that the trigger on a decocker will never be as good as a manual safety but I have heard elsewhere they can be comparable. My sp01's are fairly comparable with the same modifications made by myself new hammer lighter springs extended firing pin etcetera but I have done no smoothing of the interior personally haven't had the time or courage yet to get that far on my own.
