How do you tell whats a good sock yarn?
Either one would be ok since they're mostly animal fiber. Sock yarn needs to have a bit of elasticity thats why most preferred sock yarns have a small percentage of nylon in the blend. Otherwise the sock will get stretched out and loose fitting while wearing it. You can certainly use a 100% animal fiber blend since animal fibers are a little elastic too. The baby cashmere would probably be better since silk doesn't stretch, but the baby silk is only 20% silk so it's not a huge issue. But the fibers in both of these are delicate so I don't know how long these socks would hold up. You could knit with a strand of nylon thread to add strength and elasticity!
Personally, my favorite blend for socks is a wool/cotton/nylon or a wool/nylon blend. I like Jawoll Lang, Dale of Norway Baby Ull, Regia, Sockotta, Lornas Laces, Cascade Fixation and Knit Picks' Essential or their Bare Superwash/Nylon blend
