let's talk fuel filters

What do you guys prefer? Paper element or screen? Canister style or log type? Any flow better than others? Any suggestions on wether carbs are more sensative to particle contamination than fuel injection? Does it pay to filter down to 10 microns if the carb won't care until say 100 microns? I know everyone has their favorite brands for fuel systems, but what are the generalities when selecting parts? I am considering adding a fuel cell and redoing a section of my fuel system including the filter.
