Diamond Hard/Endurance Paint

[944fan]

We had our house interior professionally painted about 18 months ago. They used normal matt emulsion on the walls and satinwood on the doors and trim.

We have two kids, a dog, and a clumsy wife and as such the house looks like st again already. The marks on the walls wont come off, if you scrub too hard the paint comes off. All the trim is scuffed and marked as well.

Is the Endurance+ emulsion and Diamond Hard satinwood worth going for? Is it really any harder wearing? I guess as well I should go for a silk finish on the walls to make them easier to clean?
