My feeling is that for the sort of things most of us do here, a turned pin socket is the most reliable of all. Yes, soldering the IC directly may have a (slightly) lower risk of bad connections, but given that we do (or at least I do) component level repairs, may want to remove ICs for testing, etc, there is a risk to the PCB if the IC is soldered directly. As you say, cheap sockets are cheap for a reason. They do develop bad contacts!
One recalls those execrable low-profile cheap sockets from TI in the early 70s. Horrible stuff.
Aren't in fact, all wirewrap (board+pin) board sockets machine-pin? I don't recall seeing one that wasn't. Given the great track record of wire-wrapped designs that says something, surely.
