Between an eye splice and a choke knot, which has the higher ER?

The main idea here is how much of the rope’s original strength is retained after tying or terminating it, often described as the efficiency of the termination. An eye splice preserves the rope’s strength much better because it weaves strands back into the rope, distributing load across many fibers and avoiding sharp bends or bulky knots that concentrate stress. This creates a smooth, continuous profile that doesn’t weaken the rope as much under load. A choke knot, on the other hand, is a stopper knot that adds bulk and sharp changes in direction where the rope bends. These features create stress concentrations and more significant friction, which reduces the rope’s effective strength and, thus, its efficiency rating. So, the eye splice has the higher ER because it maintains more of the rope’s strength and provides a more efficient termination than a choke knot.
