Although I have no experience in combat with or without pants, I have been wearing old BDUs and other " tactical" cargo pants as my everyday go-to for awhile now. I was a demolition contractor for years and a good hard wearing pair of pants was a must. I have no experience with the higher end stuff, Crye, Vertex, etc. So I can't compare them for you but I can say that the more affordable brands like Proppers, Tru-spec, even mil- surp BDUs will hold up under the stress of a job site. 5.11 also makes some good ones, especially if you are looking for something that doesn't scream Mil or Security, though you will pay a bit more for the fashionable pairs.
Oh and Duluth makes those firehose pants that are really ready for abuse and you can jam anything you would want to have on you, with enough pockets to designate pocket for a specific item. But those are pretty heavy weight for all season, in my opinion.
