I have both the heavy weight marino wool socks, and alpaca socks. Overall, considering the alpaca socks are thinner, they seem as warm as the thicker marino wool, but in terms of comfortable wear, the alpaca win hands down.
This was my first year deer hunting with the alpacas, and being a statioary stand hunter I think it was a fair test. I'll be trying them again next season, when the winter will hopefully be colder than the 30 degrees wo had this year.... I won't be storing the marino wool socks just yet.
