Men's Hiker Encounter 2-Pack vs Men's Mountaineer Classic Edition Maximum Cushion Crew Socks: which is safer?

Where these two actually differ

• We flag Antimony in synthetic fibers (nylon reinforcement) and Microfiber shedding (synthetic blend durability) on the Darn Tough and not on the Smartwool.
• We flag Synthetic dyes and colorants, Elastic and nylon polymer additives and Fiber shedding and microplastics on the Smartwool and not on the Darn Tough.
• The Darn Tough is Merino wool blend, no water-repellent treatment applied where the Smartwool is Merino wool blend (primary natural fiber), which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
