My 10/10 is based on personal experience.
I have a very helpful contact at my local depot, she always helps when expecting a delivery, even tells the driver to leave it next door if I am out.
Also, never have a damaged box from them.
Whereas Citylink, well they have delivered me many damaged boxes over the years. One was completely open, they had not even sealed it with parcel tape. When I commented, I was told it was not their problem. :-o
