Looking closer, it does appear that the comb on the Kimber is dead level-zero drop. That makes it more like the Echols and Bridges/HCR stock.
That's how I see them also. Of course a lot depends on what the rifle is going to be used for and what you are trying to get out of the stock design. But for me and recoil designed to keep the recoil managed the two you named our my two picks.
