Ferrea because they are stamped one piece valves. kibble whites are made up of two different metals. The heads are one kind and the stems are another. They are then fused together or supose to be. They had a bad run that caused some probelms for people. I ran a set of standard ones but when I went to +1mm valves I went with Ferrea.

Sock valves are soft and the heads cup. That is why you have to adjust them more. Even more so when your running stiffer springs for a stage 2 cam and up.
