Full Service Move or Container — Which is Better?

I have clients who are moving soon, and they asked me about this. My son used a container service when he moved many years ago, and it worked well for him, but he was a graduate student at the time, and had a small amount of household goods.
Move Advocates came up with this helpful advice:
Many consumers are turning to portable moving containers as an alternative to full service moving providers, but is it the best option? Usually a container is dropped off in the driveway and you have a period of time to pack and load your own belongings. When the items are loaded, drivers pick up the container and transport it to your new home where you unload and unpack. This might be a good option for you if you are storing items while the home is for sale, but is it the best option for the actual move?
What once was thought of as a cheaper solution is now very comparable. In fact, 3 out of the 4 moves were less expensive using a full service moving provider over a container shipment solution. A sample move was not comparable at all as the container option was not available in the market area. In fact many container companies are limited to major metro areas and a few locations within those metro areas resulting in additional fees and even no services in some cities.
