Paracord is nice because it's not only strong, but also versatile. You can pull out the individual strands and use them for trapping, sewing clothes, or even suturing a wound (not that I'd suture with non-sterile material...but still). The downside is that it absorbs moisture. Not a big deal if it gets dropped in a bucket of water. But it can be a big deal if you spill fuel or something on it.
