In general Armsrong makes a good product. As I said I have installed several different brands. The toughest I have seen yet is put out under the Macklinburg-Duncan line. I actually have some of it installed as the entry way floor to a lingerie store! No damage at all in almost a year. (have you seen what a womens high heel can do to a floor?) Wow.
The armstrong line is a good product. I've installed it in several homes with families up to 3 kids and 2 adults. It does seem to wear well.
With any of this type of flooring though be certain that the install specs are followed exactly. It will usually void all warranties otherwise.
