I've tried both the Ford DEF 2 gallon and 1 gallon container with the Ford spout and I tried the Blue DEF 2.5 gallon container with it's provided spout.
The Ford setup with their spout is hands down the best. The spout snaps into the DEF port and you simply tilt the container until the DEF no longer flows. It that simple and no spills to worry about like the Blue DEF setup.
Also I choose to stay away from the fuel pump DEF sources in fear of contamination.
I typically change my oil every 6k miles and add ~3 gallons of DEF. During the winter months the trucks actually uses a lot less DEF vs the summer months.
