I have several pairs of the Smartwool merino wool socks, in the crew cut length and find them to be very comfortable for general duty use, they are soft and dry relatively quick, granted I live in NM and the air is like a brick oven this time of year. Poly liner socks are my go to socks for simplicity and functionality, I use those solely for trail running, dayhikes, and longer trips.
I also have to second Joe, the polyester Starter Duo Dry whatevs' at Wallyworld are actually really good socks for 3 pairs at $7, for weekly dayhiking, running and gym, they are sufficient and don't require you to look after them like babies when they get piled up in the rest of your laundry, I throw these in the mix during the week too. I have no fuss feet though and could probably run a mile in soggy burlap sacks for socks and not get a blister, so to each his own. Good luck narrowing things down.
