I wish I could help but I have never used the other materials. For scud backs I use Bug Skin. Really durable stuff. I might have to find some of each and compare them for what I do.

I will say that a stretch lace is gonna be different than Larva, possibly a lot different. The larva Lace holds a wire wrap really, really well and gives a super segmented look which I have never found form any other material. Everything else I have ever tried doesn't hold it shape and give the same look.
