Outer Limits 4x4 Board

Just wondering what would be better for leaf springs
Old Man Emu or Darka.
Got a one time offer on cheap springs with a choice of either.
Just wanted to know your thoughts.

most i have spoken to when researching my lift swore by OME for what it's worth. but i haven't driven either of them (made a pack with various toyota leaffs)

Thanx anyway
