With quality cut housing and good brake shoes/pads, I certainly can't tell the difference between any of them.
I have 2 brake pads and shoes on all of them, so no stock cheap pads.

Maybe I am not the princess and the pea in this instance, but I just can't say I prefer one over another when it comes to performance.
