I've got a pair of Bates side zip boys that I wear every day and they're holding up.They're comfy too.
I wear Carhartt B342 pants almost 7 days a week. Carhartt doesn't label them "tactical" and I'm not sure they qualify for it but they're by far the best britches I've had in years. I think I have 12 pair now in tan, green, brown & black. I buy them from Sierra Trading Post when they're on sale and typically pay $24/pair. They're factory seconds but I've only had one pair I could find a flaw with and that is a grouchy zipper but it works.

I've worn this belt every day for almost a year and still love it.
