My solution for this debate was to get the ZDP version and take the back bevel waaaay down to like 10ish degrees per side and then micro bevel the primary edge to 40. This knife gets used to cut cardboard more than anything, but also things like nylon bundling straps, tons of tape, shrink wrap, zip ties and anything else i run across so the 40 micro bevel works awesome because it isn't as thin as the back bevel, but the back bevel makes it a lot thinner behind the edge so it slices very nice. I won't go so far as to say it slices as good or better than an FFG, but when i'm cutting through double wall corrugated it sure feels a lot more sturdy. I tend to cut with the first 1/4 inch of the tip 90% of the time so having that thick tip is very reassuring.
I'd love to get my hands on an FFG Delica and a mic and measure the thickness behind the edge of it and compare it to mine. Although mine looks extreme, i really don't think it's any thinner behind the edge than the FFG knives are...it's nowhere near as thin as my Caly 3 so i don't have any worries about it being too thin or weak.
By the way this pic was taken before the micro bevel was put on. Someone on here called this a secondary saber grind...that's not far from the truth really. Once the primary edge bevel starts to get more pronounced that's basically what it looks like.
