Unless you are lazy and are mostly a trad climber.
why would a trad (free) climber have daisy chains on? Unless you are lazy and mostly a aiding while free climber.
Or you think for yourself and do what works for you.
Yes it works for me
So you would take up a sling and a locker. I will take up a daisy and a locker. Weight basically same. But I can adjust the length to a better change over stance. As a trad climber yes I can tie into the anchor with the rope but I am lazy and don't want to deal with adjusting the knot every time I move around while bringing up second or belaying the leader (multi with bolted anchors).
But what ever works for you. Daisy for me = easy to use, less time, less to screw up, and virtually no weight penalty. Then again I have been known to climb with a helmet on
