Single blade or 2 blade? For single blade, my personal preference in looks is with end caps, followed by barehead with lanyard tube, and lastly barehead without the tube. For use however, I think the one with the tube wins out mostly due to the lighter pulls they seem to have (in my experience but echoed by others as well) and that the lanyard can be handy.
For 2 blade, I have capped and bareheaded but don't have one with a tube. My 440c GEC #23s seem to have a lighter pull than the 1095 ones.
