Those brands have a bunch of differnt styles of skis with different qualities that you are looking for. Almost everything for what you are looking for is going to weigh within a few ounces of eachother, so we can throw that factor out the window. As for armadas, you could go with the al dentes, for atomic you could get the punx.
OF the skis you mentioned:
The most durable - DaNollies (followed by Atomics, Armadas, almost anything else, then Surfaces)
