I love the adjustability of the Kore/NexBelt. It is also thin and holds my items up very well. Being able to order it and cut it to what I need is awesome, especially as I go down in size. Since it appears that one might interchange the two, I may just order a NexBelt and put it in my Kore buckle (which I like better).
My wife has several Hank’s, but carries a small gun 
My current leather belt is a Bigfoot (steel liner). Holds up to my abuse with heavy items very well, almost a touch too stiff.
