I have quite a few Citadel paints. I also use some of the paints from wal mart. Daler Rowney and the other brand sold there - I forget the name. My personal opinion is that they seem to all have the same durability. Its really more about what is used to seal the paint. Some are thicker than others, but other than that, I really think its all about pre-treatment, application, and protection. Everyone has their own opinion though.
