Default Koyo or Screamin Eagle

I am swapping out my cam on my 107 M8. I have the option of using either a Koyo or Screamin Eagle full compliment inner cam bearings. Is one of these bearings a better choice over the other? Or are they of equal quality?

I’m not sure who makes the SE bearing, but Koyo is a top line jap company and their bearing are as good as Timken used to be. The only bearings I use in any application are Timken or Koyo.

Koyo aquired / timken torrington bearing division years ago, and produces very high quality bearings. Unless something changed recently, Koyo torrington bearings are manufactured in the US.
