If I give up the free day for less hours I sell more valuable hours of my time. However it's also nice to work with more energy and never have any dreading late hours where you'd rather rest a bit some days. I have a 4 day week but flexible enough so I can move hours over, but I only move 1-2h to my free day on average.
