I'd certainly agree with all that, the socks are by far the best mechanical filtration for using in a sump for the very reasons stated above. The only reason I didn't use them this time around is because I really wanted to experiment with the settling chamber (which would have been hard to do with the socks given the limited height I had to work with), and I wanted something I could potentially leave for a couple of weeks without touching if need be. Filter socks certainly require more frequent attention (though how frequent depends on the size and number of socks in relation to the amount of fish) but that is simply because they catch more crud.
