If you're a slave to "on time" or are worried about catching the last ride home after a charter, then I could agree with you. There can be some headaches, sure. But if you are willing to let go, view the schedule as a loose, flexible framework and understand that the schedule is driven by the customer, not Delta Air Lines, then you can open yourself up to some really interesting, rewarding (dare I say fun!?) flying. At the very least, charters can be a nice change of pace.
