I don't carry or have any experiance with any that you listed but I wil throw my two cents in for what it's worth any way.
I have been carrying an Anza knife for both hunting and general use for 15 years now. Unlike the factory mass produced knives you listed Anza knives are not edged hardened. Last but not least they are really not expensive (my most exspensive Anza was $70.00) when you consider you get a handmade quality knife.
