I have only worked on a couple older Asus computers, one being a netbook. Personally I don't think it's really the maker of the laptop, but more of the components inside it. Unless you are going to be tossing it around a lot, durability shouldn't matter too much. I personally haven't dropped/threw my laptop once in six months, always "set" it down, has no scratches on it, and the plastic is starting to come off the lid.

But just look at the components, honestly. Those Asus ones don't look too bad, not sure how those 260's are, though.
