I much prefer the carbon fiber on the gayle bradley, but sometimes it is just too wide for me. Aside from that i cant say anything that hasnt already been said, but man is it easy to sharpen. I like my edc knives to be on the slimmer side, so that is where the caly3 steps in, really more like slides in as the cf is slick to the touch, but the ergos are so good that its not an issue. It is like a luxury ffg delica, though the blade is stouter. Im not sure how i feel about the blade being laminated. i love high carbon steels as well as caring for them, so rust isnt an issue for me usually. but i guess it lets the zdp-189 be harder usual? You also have to consider what kind of clip you want to go with because both are very nice slicers and have good edge retention.
