If you have a busy homelife PBS is invaluable. The flexibility more than makes up for the small downsides. When we had hardlines I couldn't schedule things during individual weeks unless I wanted to work weekends all month. With PBS you can mix and match your work week to line up opposite of what you're doing at home. It allows me to do normal things like play softball and go to my kid's practices. If the pairings already suck PBS will not make it better but it won't make it worse either.
