I have varying styles of darn tough, smart wool and REI (thicker style with the REI) for several years now. I still can’t tell which is best. I have one pair of darn tough, iirc, that fit kinda small comparatively to my others that are exactly the same size and style. I’d recommend all tbh. Otherwise Kirkland merino wool is worth checking out I’ve heard. Point6 is another I’ve heard of but haven’t tried, the owners originally created smartwool
